stock motor, 12 sec time slips

[slowhatch82]

Alright, well...what i have so far is in my sig..

1.72 roller rockers, tmoss ported lower/matched upper, stock cam, full exhaust, 3.73 gears, sub frames, shifter, drag radials
specs: timing at 12*, fuel pressure is about 40 w/ vaccum off

I havent run the car the way it sits now...but within a month ill be sending my extra set of E7's to a friend for porting and installing 1.94/1.60 valves

After the heads, are 12's possible even on the stock suspension

It is very possible. I have a similar combo to you and have gone many 12s...

I have stock bottem end, stock cam, stock E7s with 1.84/1.54 valves, cobra intake, 65 TB, 75 MAF, rockers, and full exhaust.

My suspension is also bone stock down to the rusted quad shocks. Your going to have a tougher time on drag radials, but I also ran 12.9 on street radials, so its very possible. Just tune the car, make sure things like injectors and fuel pump are good, and then have fun!

heres a funny story before i swapped the 89 longblock

I changed just about everything to do with fuel and spark...then i just said F it and swapped motors and did the gears...ran good after that!

I got injectors w/ 20k on them, a new 155 fuel pump, new cap/rotor/wires all that fun stuff, so I guess just dialing in the timing and FP are going to be the major things to look at...

BTW I got the idea of doing the heads and valves after looking at your mods!
thanks!

it can be done with stock unported heads and intake. its just not as easy.

both of you guys have quite impressive times

Weight is a big factor as is traction - good luck though!
