OK, here we go again. I need to replace the wounded 4.3 in my truck with a V-8 and after kicking around several options I'm looking at building the 350 1 Pc. rear main I was going to use for my 383 and using the cam and pistons as well then finding another block, cam and pistons for the 383 later. Here's what I've got.

'96 5.7 shortblock bored .030"
TRW L-2441 forged 21.5cc D-cups
GM Marine hyd. roller, same cam as Ramjet 350 & HT383
256*/264* Adv Dur; 196*/206* @ .050"; .431"/.451" and 111 LSA and 109 Int CL
'415 305 H.O. 58cc heads with mild porting and 1.94 intakes
Edelbrock Performer & any one of 10 carbs from 390 to 750 cfm
1-5/8" headers.
With .045 quench compression comes out to about 8.7 to 1.
It's going in an '89 C1500 2WD shortbed stepside with a Getrag 5 speed and 3.42 gears .

Should be able to pull the truck around without breathing too hard shouldn't it?

not for sure but some of the marine stuff is reverse rotation,like i say not for sure about that particular engine but something to check.i'm talking about the cam.
sounds like it would make a good parts runner though.

Not this one. One of the guys over at Chevy Talk is running a very similar 5.7 combo with the same cam only with Vortec heads, a 700R4 and 3.73 in a '66 PU and told me it will bust the tires loose at 25 MPH and gets 20 MPG. I give up a little to the Vortecs but I can live with that, it should still get the job done. ;)
