AFR Heads

My thoughts on this tread. There's plenty of head options and block options out there. For a street car any of the TF, SM, Edde's Pro Maxx. Conventional headed race car the Bloomers. Anything that makes more power than the Bloomers needs a race block. There's plenty of used Chrysler race blocks out there. Ritter blocks are available. Ritter blocks are very good, but are expensive. But no more so than anybody else's race block, as has already been stated in this tread.

Unfortunately SBM's got a bad rep a long time ago and and has carried on into this day as being too expensive to build and make BIG power. That's fake news. It doesn't cost more to make 850 hp with a SBM than any other small block. Good parts cost, it doesn't matter what platform your starting with. For what ever reason Mopar guys are tighter with there money than the Chevy guys. As far as I know the most powerful N/A SB is a SBM with a P5 head. Like 1200 and something HP and 402".

TBH the SBM should have been the premier SB from the beginning. Taller deck, wider bore spacing, higher cam, wider oil pan rails. What kept it from that? The false thought that the SBC was better and made more power. 340 A bodies were as quick as any SBC car. 340 heads flow just as much as the infamous SBC double hump head and the 340 has a better rod to stroke ratio.

I guess find your budget and make however much power you can afford. But the heads and the blocks are out there to make as much power as you can afford.

Edit: I went back and checked. Actually the 340 head with a 2.02" intake valve flows 15 cfm more than the SBC double hump head.
