Im new here and i wanted all of your opinions
i have a 89' s-10 4.3L with a 6 inch lift kit and 38inch tires. Im almost done with my off-roading machine but the engine is a bit old and gaining mileage..approaching 155,000 =(
I kno there are alot of guys who swap out with 350's but what would be the best swap in your opinions...thanks guys and i cant wait to hear your responses.

also im on a bit of a budget..and im not really wanting to spend over 2600..so factor that in somehow.

 

sry if i confused it is an s-10 blazer not truck..if that has anything to do with anything lol

 

you can do a 350 TBI swap relatively cheap and easily. the accessories on the front of the motor are a direct swap from the 4.3 to the 5.7, you would need different motor mounts, and most likely electric fans instead of the clutch fan. Check out Jags That Run - Clicky click for the information, they wrote the book, literally, on the S-10 V8 swap.

 

on that swap would it be the older say silverado late 90's models or the newer vortec 5.7's?

 

ok im considering lots of different options...what would be more expensive tho out of an LTI and a TPI swap..well actually i kno tpi is cheaper but which is the better swap??

 

the LT1 would be a great swap, but some of the accessories have to be LT1 and cant be the same as your 4.3 for space reasons. the LT-4 is another possiblity, but if youre on a budget, they simplest, easiest, cheapest would be a 1994 V8 w/ TBI, the 1995 and up are more complicated electrically. Your computer and harness will be the most similar with a 94. The JTR book isn't that expensive and it outlines all your possiblities and the pluses and minuses of each engine swap.
