Hmm wonder how much going from a fast 78 to a 102/92 combo would gain? That's what I am currently considering after getting some aftermarket heads

IMO I'd say the potential for 15-20 hp is their with the right setup, but on most basic setups id say more like 10 or so.

Thanks I have seen that thread, it has some crazy gains even going from a ls6 to a fast 78. It will be with a btr stage 4 cam/touched up tfs 220's.. I just know how sucky the install can be on a c5
