Anyone want venture a guess on how much HP it will make. ?

GTX JOHN · 02-10-2020, 03:56 AM

Needs 425 to 450 HP to be competitive.

HP HUNTER · 02-10-2020, 10:07 AM

I would guess around 440 STP, but how it carries HP past peak would be very important to me.

Needs about 410 to run a second under in I/SA.

Jim get a hold of Tony Hernandez tony 5022 . Tony raced his corvette @ 250, 300, 365 hp. Jim Lewis would know hp.

Ok

So we know a 294 CUIN 283 4 jet can make 373 STP HP. 1.27 HP per inch.

Now looking at the 300 HP 327 combination @ 340 CUIN. Bigger bore, more compression, 1.940 intake valve, more cross section in the intake port.
It makes sense to me this engine should be able to make 1.27 HP per inch if not more. 1.27 X 340 = 432 HP. NHRA 365 HP 327 makes 470 HP.

Sounds good..if you compare it to the best 283 that ever was.
327 /365 has too much difference to base a comparison off of .

I don't know how far under you want to go , Jim, but I'm standing by my observation, using my formula that has been pretty accurate over the years.
