The Vortec truck motors are dirt cheap and run circles around the older stuff. Still GenI too no retrofitting, just need a compatible intake. They use more modern gaskets too and leak a lot less.They come as a 305 or 350. IMO once you yank those garbage heads the originalness is gone so why keep the 307 in there?

OK - what year did the Vortec 305/350's go into the trucks? And what years use the old style intake manifolds?Originally Posted by Supercharged111

96 was the first year for the 5.7L and 5.0L Vortec CPFI small block V8s
96-98 (99 as the classic, not very common) in the half tons, they lived until 2000 in the 8 lug chassis, and until 2002 in the vans. You can get intakes pretty cheap on Summit too.

Regarding the PG to 200R4, there are conversions available. That is what I'm planning on for my '57 to get rid of the "glide".

Th Powerglide is neat in a nostalgic/unique kind of way with only one shift but first gear is more like a second gear an TH350 of 200R4.

For off the line pep the biggest change would probably be the transmission or rear gear. 3.00 and a PG will sure take awhile before the revs get up much and by that time you are already going the speed limit when it shifts. 700r4 has a pretty low first gear.

How long was the PG in production? I figured once the TH350 came out they'd have axed the PG, but it seems they were in production at the same time?
