    It wasn't a "stock" shortblock, i added a set of stock bore D.S.S tw pistons for valve clearance. Other than that it was stock block,crank, and rods(with a girdle). I made 376rwhp with my n/a 302....AFM ported tw's, AFM N-91 cam, AFM modified tfs street intake, 75mm tb, 80mm mass air, bassani step 1 5/8-1 3/4 longtubes and offroad x, etc.

    I guess there isn't to many stock blocks that where built up so if you have a 306 or something like that let me know. I will probably go .030 over myself when I do this. should of expected that not to many people would build a engine and not bor it

    Boring it to a 306 is VERY minimal for power gains. I just think of a 306 as a 302......same thing.

    My combo should be close to 300 RWHP ( with out the nitrous) and i have no problem driving it around. Check my sig , heads and intake are all ported and polished and matched. Hope this helps.

    I wouldn't say "at least". I would say more like around 290-310 rwhp.

    I'm making about 325 RWHP. Also, that might be bumped to about 350 RWHP or more with an Ed Curtis cam swap.

    Anyone have comparison numbers between the TFS H/C/I and the Holley Systemax H/C/I?

    I'd be curious to see which H/C/I combos are currently the most potent street setups, considering my H/C/I is all bone-stock and I'm looking for a setup.

    Stock shortblock, 48k miles.
    Dyno'd at 287 and then added an electric fan and capacitive discharge ignition. Didn't get it redyno'd but those two changes really woke up the car so I believe I am right at 300 RWHP. :D
