Nice 4.3 engine build set-up
I am building up my 4.3 vortec out of my 98 jimmy 4x4 .
tell me your opinions and if you think it will be a good or bad combination i personally think it will be perfect for a daily driver block bored 0.40" over flat top pistons crane cam #1439811 (.429 lift ) machined & ported heads 1.5 ratio roller rockers hedman shorty headers im thinking this combo will run nice and will bring it up from 190hp stock to around 230-250hp ? any comments? |
V8!
the cost involved into getting to the numbers 230-250, is not worth it. I dont think what you listed would get you there. Drop a v8 stock at 255. done. |
I agree. You can tag a running v8 for +/- $500 locally if you know how to find them. Do either a simple carb setup or switch wire harnesses and computers and go! for about a grand you can have a v8 swap that'll turn heads.

https://blazerforum.com/forum/builds...jection-73518/ look at this i have done a lot of reasearch and searching to find the parts but it will be a mean build and its not too ridiculously expensive. also when u do that u have to have ur heads done which inclueds screw in studs and bigger valve springs to make ur vavle close and forgot to put it in there

Im also considering rebuilding a 4.3 with flat tops and bigger cam. Im either staying with tb injection or cpi since I have a new seup for it.New injectors,fuel pressure regulator.Im also going to have the heads ported and polished. |
