    Default Estimated RWHP on this combo

    OK, stock shortblock, with upgraded ARP rod bolts. 95 corvette 4 bolt block, freshened up with new moly rings and bearings on the stock parts. TFS 21 degree heads, stock as they come out of the box. LE custom cam that is 231/239 dur@.050 .571/.586 lift with 1.6 rockers on a 110 LSA. LE Ported stock intake with 58mm TB. Running .026 head gaskets, so should be 11 to 1 CR.

    Exhasut will be 1 3/4 shorty headers with a custom 3" y-pipe into a single 3.5" exhaust dumped in front of the rear axle. Stage 2 built T56 with a Chrysler 8 3/4 rear with 4.10 gears and a detroit true trac.

    Also, im doing a rear mount distributor setup, with a 97 camaro harness converted over to a 0411 PCM for tuning ability. This is going into my 93 S10 reg cab short bed. Just looking to see what some of your guys think i can expect out of this combo.

    Down the road once i get this combo dialed in my plan is to build a 383 or 396 short block, send the TFS heads to LE and have them fully ported to the max with bigger valves and add a single remote mount turbo.

    Thanks for the help and comments.

    Also, how much N20 can the stock shortblock handle safely, detonation free of course. Ive had thoughts of putting a 125 shot on it to use on occasion.

    Around 370rwhp with those out-of-the-box TFS heads on a stock bottom. With ported TFS heads sitting on a nice 383 I'd say around 430-460.
