RE: need intake and heads suggestion
ORIGINAL: 5spd GT
Can someone post up a flow data sheet for the 170cc heads?
Is it flowed at the same level? Same bore size?
Many forget about the exhaust side, and just concentrate on intake side.
There is more than just flow to heads. That is just part of the equation.
The AFR 185 has more average cross section which is very important. Shape is another HUGE factor.

51309 is the 190cc intake port and 51319 is the 170cc intake port. I compared the 170's to AFR 185's, the AFR's move more on the intake at around .500-up lift, but the Eddy heads move more on the exhaust, under .500 lift the Eddy heads walk all over the AFR 185's. The only place they list those heads though is in their flow data chart, and as an option head in the RPM packages. I don't think it's even been out for more than about 6 months, and I've heard basically nothing about it. I am impressed with the flow they get from the port size. It also runs 1.94/1.57 valves, but I'm not sure what the valve angles are. They've once again proved that bigger is not necessarily better though.

400 at the wheels? Yes, it's out of range. If you've already got the E303 stick with it. Are you staying 302? If so get some AFR 165s and a good intake. You can find some nice used stuff on ebay, a GT40, Cobra, Trick Flow etc.

And idk if I'm staying 302? Thats why I'm asking on here for someone to give me a good idea of how to make 400 hp with he mods I have. Whether that includes boring, stroking, porting, polishing, changing heads, changing intake, whatever as long as it's naturally aspirated. If it falls in my price range then great but I guess if more is needed than I'll think about it...
