Re: Molnar vs K1 vs compstar crank and rods

I bough a Scat super lightweight 3.75/400 main crank back in 2006 and have drag raced it on and off to this day. Thinking about retiring this rotator next year for a 3.875 setup. As nice as this crank is, I wouldn't spend the extra money again. There might be some benefit to the light weight, but it...

Re: Sbc 400 vs 415 vs 427?

Re: Best head for a boosted SBC

What pump gas supports 24 pounds of boost, even at 9:1? EFI? Knock sensors?

I would have though that much boost would be C-16 territory.

Re: 4150 4778 Holley carb questions

If the carb hasn't been molested, just do the rebuild, put in the stock jets, and tune with the AFR gauge. ( a cam with lots of overlap can give you a falsely lean reading at idle) If the passages are full of crap, it's messed with, or just a lemon, you might never be successful with that carb. Both...

Re: 1400 hp Big Chevy combinations

I really hate it when someone slaps together a half-assed engine and procedes to scatter it all over the track. Now everyone is stuck sweating their butts off in the staging lanes for an hour waiting for the track to get cleaned up. It sucks even more when you are the next one down that lane and lo...

Re: 1400 hp Big Chevy combinations

Then perhaps you should have been clear in your original post of the goal and guidelines rather than coming off as a junior poster with an outlandish request.

Re: 1400 hp Big Chevy combinations

Maybe you can clarify for us the application and intended use.

I watched a fellow racer wad up his 1968 Camaro last season at about 160 mph at the strip, too much power and not enough car, thankfully a 10 pt cage allowed him to walk away.

With great power comes great responsibility. =D>

Re: 4.310" 5/64 ring 4032 alloy 200hp spray questions

I see no point in pressurizing a thick ring. Total seal likely makes a drop in ring set that’s much thinner with a gas ported ring spacer for the top ring, might be worth talking with them directly on their opinion.

Re: Critique my Sbf combination

Let me throw a couple of darts at your proposed combination. You said flat top pistons, should be 11:1 Calculator shows 9.6:1 at zero deck and a 4 cc valve relief. Grafting A dominator flange on a 4150 intake without addressing the plenum is doomed to fail. We dyno’d a large BBC that had a World sin...

Re: Big Block Chevy Oval Port vs Rectangle @ 20 PSI Boost

Crank driven compressor I would say the larger head no doubt. I would have concerns (not necessarily accurate) with spooling/building boost with the large heads and a turbo.
I would love to know if there would be an issue.

Typical FM hypereutectic piston, flat top with as much volume as a dished piston.

Re: Vacuum for vac u pan

If you're not using a mechanical fuel pump why not plumb the inlet side of the biggest SOB mechanical fuel pump you can find to the crankcase as well?

Re: Under performing 357 sbc

Get that engine on a dyno, cam timing, tuning, and the resultant graph can help with converter and gear selection. Knee jerk response is you need more converter stall. 350/glide is yawn inspiring. More cubes would definitely help.
