I searched and couldn't find the build. any chance for a link ? thanks.
*** I found it, August 26/2022 author Jeff Smith.
Want to build a stout engine but not spend too much money in the process? We assemble a solid and reliable Chevy 350 small block for less than $3,600.
that ain't a Vortec motor.
Author Jeff Smith's says pal Bill Irwin pulled it from 1990 Suburban. What'd that cost? & what happened to its heads & valve covers? What'd the machine shop labor cost?
Smith used those dang cheap hyper rebuilder pistons w/ short 1.540" compression height and thick tractor rings. Pizz-Poor.
No mention of decking block (&yes I read specs); if not, pistons likely ended up some ~ 0.045" below deck. Because Smith got new deck pins, it was probably decked. Pizz-Poor.
Smith got some china kinda-sorta copies of vortecs. Perhaps OK
Smith states Vortec heads have 110 lb springs; maybe the chinesium heads are 110, but OE GM Vortecs' springs are still about 80 lbs on seat --- like pre-roller springs --- different springs but same seat pressure.
Smith states it's a roller-ready '90 block (can accept affordable OE roller lifters) but opts for cheap hyd flat tappet cam. Smith spent about $115 on cam kit BUT might've gone roller for some $250-$300 more. Pizz-Poor.
Smith picked summit M55 pump w/ 5/8" pickup --- should've picked melling M155 w/ 3/4" PU. Meh!
Nothing really wrong but but me thinks it might've been Much better for not much more $.
next time, begin w/ a real Vortec L31 junkyard motor.
