9:30 Right, if you have deep pockets, sure you can do it. In the end, I have a bare basic 454 bored .60 over to 468. A pair of oval port 781 heads and a mild cam. A performer dual plane intake and a 750 dual feed double pumper. It makes 550 ft. lbs. of torque at 4200 rpm and 500 hp at 5700. All on pump gas. As cheap as you can. No high cost roller shit. It's more money than you need to spend for the same result.

When you say install “straight up” do you mean just install it dot to dot? Reason I ask is because my cam has a 111 ICL and a 114 LSA and I was looking into if it needed to be degreed because it broke 3 valve springs, luckily they are dual so I didn’t drop valves

My dad bought a new Ford pickup in 1967 . The Ford dealership replaced the clutch do to shifting/dragging problems twice before one of the techs checked the bellhousing and found that the bellhousing was apparently drilled out of alignment . You never know ............

This is way off. I run the numbers on the Boss 429 and it came up with 551 hp. They only make in stock form around 430 hp on a dyno.
@jeffsmith2003 9 ай бұрын
As mentioned in the video, this simplified HP estimator is just that - an estimate that assumes (there's that word again) several things like a really good camshaft that is likely a roller with more lift than a flat tappet. Plus as mentioned several other variables. I ran the numbers to get your 551 hp at 6,000 rpm. The Ford numbers of 450 lb-ft of torque and 375 hp is using a stock and very mild flat tappet cam with a stock intake and cast iron exhaust. If you put headers, a better intake, a nice hydraulic roller cam, and enough carburetor it would probably make 530 lb-ft of torque and somewhere around 550 hp. If you tested a bone stock 429 - it will probably make more than the factory numbers - the OE's often under-rated their engines in order to pass through car inssurance regulations back in the day. Plus, the Boss 429 was rated at 5,200 rpm peak hp - way short of what you plugged into it at 6,000 rpm - do the math - with 1.25 x 429 and then peak hp at 5,200 - it comes to 475 . So it should be obvious that rpmplays a big part in this estimate. We are working with 20 to 30 variables here and yet estimating power to come up with a single number as the result. These are just estimates - it's possible that the Boss 429 isn't capable of 1.25 lb-ft per cubic inch. But I think it probably is - again assuming everythign else. Also consider that this 1.25 lb-ft/ci is based on using modern combustion chambers - which is what establishes combustion efficiency. A Boss 429 chamber may not be that good. But then again - it might be capable of actuall more since its close to a hemi chamber.

What would u recommend I got 454 gen 5 what kind of heads and carb u recommend it has a 520 280 Comp Cam
@Danno74Z 9 ай бұрын
You said at the beginning of the video one has to be within .001" inch of concentricity - FALSE. One has to be with .005" run out or .010" of total indicated run-out. So if one has a reading of 8 thousand on the dial indicator their run out is 4 thousand and within spec and they don't have to do anything with offset dowel pins.

Hey Jeff I just watched your big block combo video I have a 427 that's 0.60 over so a 439 it's 10.5 to 1 compression it's got a Howard's hydraulic roller 235x241@50 with 618 lift and a 108 lsa it's got a forged crank good gm dimple rods and a set of AFR 265 oval port heads it made 661 hp and 605 torque on the dyno I know this is a great street combo but I want it to be a Lil more nasty I have a comp cams xr292r solid roller that is 254x260@50 with 660x666 lift on a 110 lsa what's your thoughts on doing this cam swap I don't mind the Lil extra mantnince with a solid roller?

I have always used a piston "stop" degree of 30 + / - in either rotation! Jeff's 47 degrees ensures even more accuracy.... but is not necessary. 30 +/- is near perfect. Keep in mind that this is not limited to camshaft degreeing.... it also serves as an excellent means for locating true # 1 TDC that can be used for Ignition Timing as well.

The pointer is adjustable so that you can split the "stop". The degree wheel, once attached, should NOT be moved against the crankshaft.
