I use a f303 cam with my STOCK e7's (I removed the exhaust hump, milled them to 58cc, and put TFS locks, retainers, and double springs on) with a cobra intake and a 65mm throttle body I made 253rwhp/280rwtq, infact 30 more RWHP then I made with the SAME engine combination and a STOCK cam. I make power to 5800, and shift at 6000. That was 100% Untuned, no AFPR, no chip, nothing. I run 94 octane gas and my base timing is 17*.
I'm not saying E7's are GOOD heads, they are junk. I am saying that you can make DECENT power with them if you have any clue what you are doing. If I had some afr's or TFS heads I'd be close to the 300rwhp mark.
for comparison, With all the bolt-ons I have I made 200rwhp. I put my E7's on, with a cobra intake 65mm throttle body, STOCK rockers, f303 cam and a 70mm MAF and I picked up 53rwhp. This was on a new shortblock too, which was much tighter at the time, I bet it makes 260 or so RWHP now. It traps 102-101mph in a 4,000lb car
