Don't have a lot of time here. Going home. Heads are everything. More tomarrow. :drink:

As long as we use Fel Pro MLS gaskets we should be fine without O-rings. I'm running a set of AFR 165s on the Cobra with 9.2:1 compression and 10psi of boost and haven't had any issues with them.

As for head size that depends a lot on the specs of the cam. Joedls, do you have any idea what the specs are on that custom grind cam? We are talking about only 302ci so we don't want to go too big unless we are going to rev it really high (above 6500rpms). And if that's the case then we need to ditch the hydraulic roller and go to a solid roller. Hydraulic rollers in the 5.0 are only good to about 6500rpms. I think something around 185cc to 190cc if the cam has 220 at .050 or more. If the cam has less than 215 at .050 then something in the 165-170 range would work well.

Ben, I'd pass on that 8.8. One, it has drum brakes and two, it only has 28 spline axles. Also, I'm fairly sure that it will have to be narrowed to fit under the RX7 but you could measure and see. If you want to go with an 8.8 get one from an Explorer that already has disc brakes and 31 spline axles.

I agree about the MLS gaskets. I used the Cometics on my 347 with 12 PSI of boost and 9.7:1 CR, no problems.

I really can't say what the specs on the cam are. I couldn't find any info on it. I think I'd go with 185cc or 195cc with that blower. You really want to minimize any restrictions so the blower can do its job.

Heads make the engine!!!! All the engine does is stay together!!!! AFR FTW!!! 185 or 205!!! 185 will do the trick, with Nitrous exhaust ports, http://www.airflowresearch.com/185sbf_strp.php

I kind of jumped a few pages.... what is the short block??? year? roller? what is done to it? Compersion?

My fox ran 11s with a stock block 9.5:1 cast pistons 351w, with a lot of blow-by, with a set of AFRs!!! 11s, it only dyno 325hp to the wheels!!!

The biggest question is how fast you guys want to go???

I agree about the AFRs, I like mine.

Canfields are also up there with AFR.

Check these out, they come with a 660 lift cam. Yeyah!

Those are pretty. Would it be good on top of our 302 for a blown application?

after Glen opens these up a bit.... yeah. anyone know the info onthe block? year? roller? what is in it? If he will take $500 yeah.

Forged 302 bored .030 over, custom grind roller cam specifically for blower, reconditioned E6 iron heads with dual springs and 1.6 roller rockers.
