Re: the big swap!!!
:work: why go to the 4.3???? That doesn't make much sense money and workwise, either 3.8l or v8 that thing and it will be easier and possibly cheaper for ya.Last edited by 97rs4life; 10-30-2006, 04:09 PM.Comment

Re: the big swap!!!
he is probaly thinking about funding.....it is probaly alot cheaper... what kind of power does the 4.3 have.. if it is close to the same then it does not make any sence. i am stuck on a little fence myself right now... i was thinking of building a lt1 and slaming it in my car.. or a 383 stroke... i have not decieded yet.. ahh screw it were is the nearest 572 lol....Comment

Re: the big swap!!!
Swapping the PCM is going to be a big PITA I would think. Would the stock K-member work for the 4.3? Probably need custom exhaust, well Y-pipe anyhow. Will the 4.3 fit up to the tranny of an fbody? Lots of varialbles to think about...
I'd go with a 3.8 or V8, probably cheaper and more mods are available for them than there are the 4.3. Guys who mod mini trucks swap the 4.3 for carbed 350's with no computer. The 4.3 is built for low-end torque, the top end power sucks.sigpic

Re: the big swap!!!
the tranny from a v6 fbody will not work on any 4.3, the bellhouse pattern is differentOriginally posted by gugdathug3
and you will need a lt1 front crossmember or the 4.3 wont fit(the 4th gen v8 crossmember sit lower)
the 96 and newer heads flow great and would make good power with a cam and lightweight 9.5 cr pistonsWolf<br /><a href=\"http://www.cardomain.com/memberpage/249111/7\" target=\"_blank\">95 black t-top camaro</a>,3.4 5 speed,ud pullies,plugs/wires,de-shaft tb & gutted airbox, homemaid short throw shifterComment

Re: the big swap!!!
Since a 4.3 is a 350 minus two slugs he could get forged rods and pistons for it.1995 Patriot Red T-Topped Z28 A4<br /><br />Mystery rebuild in progress.<br /><br />Soon to have 383 ways to beat KBreezy and Shane. :DComment

Re: the big swap!!!
ok i missed alot here ...
1) one of my buddies buddies wrecked his jimmy and wants 500 for the motor
2)i work at advance auto=sweet discount and access to uber info
3)mines a t-5 manual so it should bolt up...being it was used in a s10
i've got the swap figured out...i just want info on things like heads, intake, cams,...o and its a vortech with 80,000 on it...so it'll go foreverComment

Re: the big swap!!!
Your tranny should work fine, but you need the bellhousing from an s10 to go between the engine and tranny. The 4.3s use the v8 bolt pattern.Originally posted by nightrider292 S10 3800 A4(96)<br />1/4: 14.374 @ 92.25 w/ 1.976 60\'<br />Turbo and 12\'s Coming Soon!Comment
