Have you built a LT-4 stroker?
Well have you? What did you build, What parts did you use? We're you happy with the results? What would you do different?

1992 lt1/lt4
Line honed, bored, decked studded and blueprinted 4 bolt main block
Afr 210 comp port heads
Jessel 1.6 shaft mount rockers
Hardened pushrods
Comp 280 XFI cam
Vigin Lt4 intake
BBk 58 mm throttle body
60lb injectors
Aeromotive fuel pump and regulator
Eagle 4340 crank
H-beam Rods
Srp pistons 10:1 compression with 65cc heads
ARH headers and Magnaflow 3 inch exhaust
Canton Pan and valve covers
P600B blower with intercooler pushing 7 psi now
I am happy with the overall results of the combination I used. It is making 448 WHP at 6500 Rpm with only 7 psi. I plan on changing pullies and adding meth/water injection next week. We are hoping for 12-14 psi and roughly 550 whp.

FWIW im hoping this fall to beat the above time and I feel sure with more stall in the converter it would go into the 10's

we had to get new bolts. The ones eagle supplied were crap. Also the angle is getting you into the water jacket if you are not careful. There is another brand, and right now I cant think of the name of it, but they are splayed but at less of an angle.

Been happy with mine.
LT1 2 bolt block with splyed caps
Callies Dragon Slayer crank
Lunatti Pro Mod rods
Custom pistons .040 over, 11.5 comp
Custom Comp cam 242/248 .576/.599 w/1.6 rockers
Ported LT4 heads w/stock valves
58mm Tb, 30pnd injectors, Edelbrock intake.
Runs 10.8 in good weather, 11.20 in the bad heat. It is pretty consistant.
I've been running a mail order tune from Ed Write all these years. I would like to get it dyno tuned but never found anyone local that I would trust to do it somewhat local.
