I'm not sure that you need forged crank and pistons for that if it's not at high rpm for long. I was able to get 370hp at crank with milled and home done cleaned up vortecs circle track cam with just under 0.5 lift performer rpm intake and stock bottom.r I eventually damaged a piston using nitrous but it would have been making well over 450hp at that point. Notched he bore around the valves and added ring gap. Went ok for a 305, revved close to 7000 rpm. If it's sustained high rpm, boost or high comp than forged stuff be good idea but for street or the odd drag race with careful tuning might be ok with stock stuff

You do not need forged stuff to go 7 grand, unless you're going flat out around a high bank oval. Drag racing you're only at high rpm for a few seconds. Stock sbc cast stuff does fine.

305's last a good while smacking em to 7 on the street.. hell, they last a good bit seeing 7 plus regularly balls out on the dirt track too without forged anything for that matter. Oil supply with a windage tray and baffled pan is crucial at that end. That's just a hobby class. Racesaver 305 Sprint car class the motors crank out 470-480 horse on a solid lifter 10.75 compression. Brodix "French Grimes" heads no porting allowed. They are forged. Not an exotic setup. Very basic. Those engines see 7 or 8k, occasionally the tach strikes 9,000 rpm coming out of corners. But here's the catch, they just last and last. You'll get 3-4 seasons out of it, no problem. 358 class you'll see 600 horse but it gets more cost prohibitive by a good margin, and the engines don't last all that long.

It is an interesting vid. A lot of people have 305s, in these 80s and 90s classics now. If you do not have an HO or votech 305 (most people don't), you can do a lot with it. First off, I looked it up. They come with 0:1 compression, from the factory. You can advance total timing, A LOT, without causing knock. Delete a spring, and add heavier ignition advance weights. All of a sudden, it wants to burn one tire off. Shit can your quadra junk, and put a holley 450. I went from a 600cfm carb to a tunable 450, and it responds like a 350. Add an underdrive crank pully. You will also need to get a smaller alt pully, so you have voltage, at idle. That makes a very big difference, and for cheap. I have yet to upgrade to electric fan and water pump. My clutch fan weighs as much as a bowling ball, so I know there will be very noticeable gains, there. So, you definitely do not have to be sad, just because you have a 305😂

Biggest problem w the 305 Chevy engine is too many Dummies want to use a 350 style cam in it (112 lca). It needs decent heads, w/ 1.94 in and 1.5 exhaust valves. THE XE cam was a great choice with it's 110 lca.

[@shaun4bigblocks993]

I have a question... why is a 5.3 with a 3.78 bore considered kewl but a 305 with a 3.736 not? You do know that 305 Vortec heads, though missing the 350 style ports, still flow like LS or Fast Burns, right? Why build one? Same reason you build a 5.3- because they are cheap and most importantly thay can handle boost WAY better than a 350 because of the thickness of the webs between the bores- dugh. And also because like you said, where do you stop? Another reason, you can keep low end torque lower thannon a 350 yet make it rev for any HP level you want making tranmission builds cheaper. You can also stroke it with a 350 crank and make an extremely light rotating assembly that will easily rev high. The magazines used to do it with ported S&R Torquers. Any engine can be built to perform, why do you think import guys build 4 bangers- and they aren't light like they were in the 90s anymore.

[@dustinmccain1215]

its a sbc. It can be made into a nice street engine it just costs more to fool with than a 350...and the 350 will blow its doors off with the same upgrades.

use vortec heads or AFR heads for a 305. the crank is the same as a stock 350 you just have small bore, so overbore +.o3o" to help unshroud the valves. you don't need vic jr intake an rpm would be fine. use a hydraulic roller cam like comp cams XR276HR if you have afr heads your gold.

[@jarrellwilliams2562]

7 months later bro I have a 305 1985 el Camino , I just need a break down of what overboring is ? How much will it cost ?

[@zAvAvAz]

@@jarrellwilliams2562 well you can bore a 305's cylinders out + O.O3O" over the size it is stock for larger than stock valves- although you may want to less like +O.O1O" or something if have stock real small valve, this shall clean up the bore and unshroud valves a bit and its enough to make improvement, but what you really need is deck hieght to a zero deck measured at each 4 corner pistons it should come to 9.O25" stock, or pistons down the hole O .O25" about the thickness of your pinky fingernail tip if you got thin ones like me. so you want to take that O.O25" off the deck surface and have a 9.OOO" deck hieght and then use some great gaskets like felpro and get it O.O39" thick although you could get a O.O4O" also. this gives you perfect quench, i would say oh 500 dollars for both maximum on the high side. or you can hot oil bathe it and spend more but its worth it to replace cam bearings and clear out the coolant and oil passages real good and run some high pressure through there to make sure to get it all out and use wire brushes that reach deep and blow all that crap out of there. Now you'll have a great oiling system to last a long long time. i would just get a dart 400 small block with 350 mains and use your 305 crank in it and bore it to 4.165" use your 305 heads . put in an XR282HR comp roller cam or magnum 280H10

In NHRA K/SA we are limited to 9 inch wide tires so I make it up with a 4.56 gear. Theres a guy on the West coast who took the class record for my class down to 11.50s with a 305 in an 87 trans Am.

I built my 305 for cheap 20 years ago and it was a fast car, much faster than stock, in a 1984 firebird 5 speed, faster than a 5.0 mustang ( stock) and even the new 4.6l at the time. The issue is now 20 years later the world has changed. Building a 305 is a classic move and really just fir historical purposes, now an LS is commonplace and tough to buiild a 305 to even get to stock levels of an LS1,

[@LSxHunter]

I honestly want a 305 for the strict reasoning of because I can 😂. The head flow on these newer engines is absolutely mind blowing compared to even some of the aftermarket SBC heads. A 5.3 with a cheap cam makes gobs of power but you can’t go to a cars and coffee without seeing 5 LS swaps. I’d love to build a turbo 305 for the sheer “because” factor.

​@@LSxHuntertrue, a turbo 305 would be interesting, the small bore and bad head flow is actually better for a turbo? Im not a turbo expert, still back in the day of 1990s mods where lots of people were still scared of computers. A lot of 1980s GM cars the big deal was a built 350 with no computer.

@@LSxHunter so far, the cars or classics I own today are original engines, modified but not crazy, none have stock heads.

It makes me sick of the idea of redoing a classic to electric, if you modify a classic too much, just go buy a new car! If I still had my 1984 firebird I would probably still run the 305...

This is just silly.. by your thinking , you really shouldnt "waste your time" unless its a big block ? I mean... why do a silly thing like a 350 when for similar money ypu can just build a 427? Or 454? .. I ,for one, would be quite happy with a 360 h.p. motor. Not to mention , as a daily driver its likely to get a bit better has mileage with a little les cubic inches. So your seeming to put it down as a waste of time and money is WAY of the attitude and objective of the hardcore, passionate true "hot rodder" .....

I mean, if you making a strictly race car, displacement wins. I drove and road raced a 305 for years, car was still a ton of fun. My daily is over 400hp and I get bored with it fairly often. Coming off of being in 600+hp cars, it's all about perspective and goal.

Ill be thrilled with that. With a speadbore I may just still have decent milage . Same with my 70 Camaro SS .. If i want to just build a beast, the block I start with will be FAR more important.

I traded a 71 Chevelle Malibu with the 350 4BBL for a brand new 79 Monte Carlo with the 305 4 BBL. Big mistake. I was in my early 20s and laying lots of rubber with the Chevelle and it never missed a beat. On the other hand, the Monte couldn't get out of its own way. Dished pistons - ugh. After only 70K miles of gentle driving the Monte had bad valve guide seals and two plugs fouling & needing replacement every 2K. I'm 65 now and have never owned another 305.

Honestly - in my mind the 305 NEEDED more power to stay healthy. I feel like some of my longest lasting engines are in that 350-400 horsepower range, meanwhile the lower horsepower stuff fouled itself out constantly.
