allright guys i need some info from some experince here,

what i have done to my 89 vert is full MM road and track box, sn95 5 lug conversion w/ cobra 10th anniver calipers w/ powerslot 13" slotted rotors, sportin 2003 cobras w/ 275/40/17 555Rs out back and 555 extremes up front, 3.55s in back w/ eaton posi, 31 spline mosers and c clip elims, FR alum ds and safety loop, TKO 600 w/ mcleod scattershield and mcleod clutch, as for motor, original 2 bolt main, w/ scat 4340 crank, eagle h beams, JE flat tops at 9.1, RHS heads, comp extreme energy cam .565 lift, got edelbrock performer rpmII w/ 75mm accufab TB, and pro-m 80mm MAF, northern alum radiator, black magic extreme ele fan, crane cam HI-6R ignition w/ rev limiter and boost retard, 42lb injs, 255lph pump, hooker super comp 1 5/8" shorties w/ 3" collector w/ full 3" flows out back, MM 6pt roll bar w/ swing outs, its not completely done yet motor goes in next week, i think it will pretty much top this stock block out but i still think i want to super it and destroy what i have built, if i were to go with a s/c which would you recommend, i will probably be pullin it again and putting it in a dart block soon, suggestions will be appreciated, was looking for a 500RWHP car now i want more, but still needs to be streetable, thanks

2 bolt main block is only godd for 450rwhp, past that and it's only a matter of time..............

10psi s/c on your engine should get you real close to 500rwhp though.


Get a Vortech s/c or Hellion turbo would be even better

Black Snake

Keep the compression low and build the bottom end and your car will be up to 500 hp easy.

i thought the stock block was good to about 5-550 rwhp

ruger311

i think stock is good for 500 or so RWHP i have a friend pushing 742 to rear wheels with stock block has made over 100 passes and not blew anything yet,,, jasper how you like your 347 and your shot of nos,, what are you putting down? any track times?

supercharger you should see about 500rwhp.

Also, without a blower those injectors are a little big for your motor.

ruger311

yeah i know they are a lil big but am planning on s/c or turbo so didnt wanna spend another 300+ on another set of injs, should be fine for now,

ruger311

oh yeah any suggestions on s/c for right now, going to buy another fox prolly a notch soon and do the twin thing on it, for this one prolly will stay s/c, what is the difference between S and T trims?

wish i could tell ya in all motor form it kicked *** compared to what it use to. i still need to get it tuned to find out what i put down. when it was on the dyno i ran it to blow by issues and it was spitting out oil everywhere and i just got it worked out. but i need to save up more tuning moiney cause i had to use the orginal money i saved up for rent but give me a little bit longer and i will reschedule it again and post up the proof. but i am hoping for 280-325 thats what i have heard she should make on motor and at least 400+ on spray and over 500tq.

but for a good supercharger i would recommend vortech or procharger thats the ones i have nearrowed it down to. i want a vortech v2sq or procharger d1 w/3 core intercooler and run around 10lbs of boost

ruger311

when i get it up and running and then get it broke in then tuned run it for a while then get s/c, was leaning towards the procharger, let me know how she runs with your new tune
