Hello, this is my first post here. I thought I'd introduce myself. I am 19 and not new to engines or cars or trucks. I have rebuilt many 90's small block chevys, ford 5.0's, 1 351w, and a few gm v6's.
I have a 86' S10 that my dad and I have restored inside and out... it simply awaits a new more powerful powerplant and matching drivetrain.
My goal is for a 10:1 "425 reliable hp" 383 91 octane street motor, on a 2 piece rear main seal block. I am thinking of using the Scat 1-40805 Forged rotator kit, then have it balanced locally. A retro roller setup with a XE282HR cam, with worked over 906 casting vortec heads with proper valvetrain.
My question is, since this is my first build using a block older than anything I have worked with, did I pick a good block to build on?? I picked up a virgin 1978 3970010 4-bolt block out of a big school bus for $50. No part of the motor showed abnormal wear.. All bearings looked good, cylinders looked good, piston skirts looked good.. This block has the cast 3412 main caps and only has "010" casted under the timing cover and near the oil filter. I have been doing hours of reading trying to figure out if the late 70's 010 blocks are thinner or weaker than the older ones, but I cant get a definate answer with this homework. Do any of you guys have any input on this?
Basically I dont want to pay for machine work for a stroker, just to find out these are weak blocks, haha, thanks!
