Here is the build on the car I just bought last weekend.

86 SC, 305 LG4, TH700R4, SLP headers, 3" cat and exhaust. ZZ intake, Mild cam 204/214, .423/.442. SLP shift kit, richmond 3.73's w/limited slip. Suspension Techniques Sway Bars, Globel West Wonderbar, Poly everything bushings, Metco LCA's, Lakewood Panhad Rod. 16" ROH, with BFG G-Force KDW 245's and Tokico springs with 5 way shocks. Formerly 86SCBJN's ride.

I like the car a lot, it handles like its on rails. Its runs well too, other than a wierd electrical problem that causes a miss at lower rpms only, something or other in the ignition.

I'm curious as to what you guys think the effective powerband of this build is. The car feels real strong from 3500 on up to 5500, I haven't pulled it past there for fear of the stock valve train not liking it. What do you guys think, is that too far, does the cam support that, etc...

 

That's the summit 1102 I think. Look it up and find out, I think they say 1000-4000RPM or something. It's a generic cam, made by everybody out there. I would upgrade the springs on it, if they haven't been yet.

The rest of the car sounds pretty good, fun ride eh?
Slower than your TPI IROC?

 

Not by much. Its softer on the very bottom, but it pulls almost as strong everywhere else, and doesn't fall on its face like the TPI350. The rest of the car is a no-contest, the interior in this thing is 4th gen leather, z28 dash, nice radio, etc. The car is way way tighter too, no t-tops, everything works, and the suspension is AWESOME. Good rubber, everything is a-ok with the exception of a weird occasional stutter I'm getting thats almost certainly the ignition. I'll track that down eventually...

 

I checked it out, your are correct, that is the Summit K1102. They give a usuable rpm range of 1000 to 5500, I guess the dovetails nicely with what I've felt the motor likes. Its a crate motor, the 225hp RV cam motor originally, I have no idea what heads and valvetrain that is, I figure its probably ok up to 5500 every now and then, sure does pull strong all the way there.
