479 HP! Vortec Heads w/ Roller Cam VS Flat Tappet (Dingle Ball 2.0 Dyno Results)

Can we make more power with less compression, less duration and less head flow? This Vortec headed 355, I call the Dingle Ball 2.0 is put to the test on the dyno to show we can make some great power with a roller cam VS Flat tappet.

You have proven again that you can run a noticeably smaller roller cam and make similar power to a larger cam. The Vortec heads always amaze me in that they a lot of times make more power than a better flowing head. That’s one nice thing about small 170cc runners flowing 230 ish com.

Killer combination is an understatement! What an awesome comparison! I still find it difficult to dig that deep into my pockets to buy a roller cam, but there's no doubt they're good.

I'm traditionally a Big Block Mopar/Big Block Chevy guy, but.. I've recently stepped into a jet Boat project that's gonna be powered by a 6.0 LS. Totally different animal, but wow.. the parts availability and ease of making good power with the LS platform is hard to deny. High performance roller cam and lifter kits from Summit for less than $450 !! And the heads flow amazingly well in stock form. Power with an LS is like shooting fish in a barrel... pretty cool in my opinion. 🍻

@@Torquemonster440 True to a point. A stock SBC roller block isn't too bad. A good cam and lifters are about $500. Still huge compared to $250 for flat tappet, though.

Also, if someone were to reuse the factory roller lifters, a Summit Pro series cam is about $250 for just a roller cam. But again, for my application I don't think it would be worth the money to do the swap.

[@zachniverson8816]

I think you should definitely use the 2.0 heads and cam on a 383. But also use an Edlebrock rpm air gap thats port matched and the ports cleaned up with that same spacer. You'll gain SOO much more low speed torque and with the porting and spacer you wont lose very much top end at all compared to how much youll gain down low. Also I would raise the compression back up to 10.5:1 and run 93 octane for all of us that do have 93 at the pump. I believe youll see 500hp or close to it peak but lower rpm gain will be impressive. I woukd really like to see this combo man

I have a howards rattler cam (HR) im wanting to try in similar setup with aluminum heads. Curious how close to this 1 itll be

[@robertwest3093]

Did you use the thick old style 5/64 thick piston rings? I would love to see a test between them and a 1/16 or 1.5mm set and also a 1mm set. The only tests I’ve found haven’t included the 5/64 rings. The OEM’s went to 1/16 or 1.5mm in the’80s and now a lot of engines use 1mm-1.2mm sets. I would imagine the difference between the thinnest and the thickest rings would be 10 HP I would imagine.

[@bdugle1]

I’m guessing that hp carry at the top on the “1.0” engine is the longer exhaust duration. The fatter torque curve on the”2.0” is probably the bigger lift and more area under the curve of the roller vs flat tappet cams. I like the 108° LSA, I don’t remember if the flat tappet cam was the same, but that could fatten up the mid-range too. For myself, with intake closing in the mid 40s (at 0.050”), I would take the 11:1 build. All together very nice work! Thanks!

If you were going to build a mild turbo 350 like 500ish hp do you think the crank and rods in a 88 truck 350 (originally a TBI) 4 bolt roller short block hold up , this is just a cruiser hotrod street truck with normal occasional just havin fun use not for the strip. I know its not ideal but I'm thinking probably for a while.

[@cuttersperformance]

You'd be supried how strong a stock crank and rods are. As long as everything is in good shape, keep it out of detonation, you'll be fine for 500 hp all day. Forged pistons are a good idea, but I've used Hypereutectic pistons at that power level with no issues

[@conservativecrusader80]

90% of the time when flat tappet cams go bad on a rebuilt engine it's because people don't hone the lifter bores. Lifter bores usually get scored during tear down, which keep the new lifters from rotating. If the lifters don't rotate while the engine is running, they WILL get destroyed along with the cam lobe.

[@cuttersperformance]

Agreed, if they can't spin freely she's toast

[@cuttersperformance]

You can, and I have done 11:1+ on SBCs but it's not quite as easy as LS platform. The LS heads are very efficient and require less ignition timing, and the cooling system of the LS allows better coolant flow through the heads to prevent hot spots and cooler chambers. Back when GM built the 11:1 SBC the gas was much better than today, the timing often times needs to be dialed back to run todays gas without ping

That was in a k5 with no issues. Not even a very large cam.....small really.
