Just don't understand all the work and money for little "maybe 20hp". Also now you've moved the curve. So now you gain 20-30hp above 6-6500rpms? Loose 20-30hp at 2500-5k? How's the stock engine handling that? Float springs / valves and what not, unless you upgraded them.
Just add a 75 - 125 shot, she'll take it all day long. fuel system good to 125shot. Same price nearly as cam swap. less work.
Definitely curious to see. It's probably not going to read to well on a dyno. Better results taking it to the track. lol Cheaper also.
Uhm, "all this money" needed to be spent anyways. I needed a new engine. I had wiped out cam lobes on the passenger intake and exhaust cams and had metal shavings go through my motor, and had a blown head gasket, and piston slap, so regardless I was already looking at a rebuild. The only non-factory parts used on this build were the Kooks headers (used paid 400$), Ford GT supercar rockers (300$), heads were ported for free, Accufab TB was 300$, JLT was 200$, those "cams" you mention were Factory take outs from a 96-98 cobra, I paid 200$ installed for them. The cobra intake was 400$. What is that like 1800$ plus rings, bearings, gaskets, and the cost of pistons and .020 overbore? The whole new engine was somewhere around like 3K which is less than what a factory OEM ford 4.6 4v crate engine costs.
