Default Re: Let's build a drag race 8BA engine

Food for though.....

HP costs money but HP per CI, can cost a lot more. HP per CI, is what wins races in class racing.

Now a days, you can easily build a 304 to as much as a 315 CI FH, using the 4.25 cranks. But, because of the little 1.312 ID intake port, each time you go up, in CI, you gain total HP but, loose HP per CI. Even with a blower, you can't get much threw that port. I would bet a Built, N/A 302 SBF will put out more than a blown FH of the same CI.

You gain some on C/R as you increase CI but, you loose breathing ability. For the street, CI helps and blowers help but, you'll never win a class race that way.

The old saying "speed costs money, how fast do you want to go?" will always apply, especially in class racing.
