ok...fun swap

[nightrider2]

ok heres the plan...the 3.4 is a little small for my taste and the 3.8...well i had a car with one...no fun...so i want to swap a 4.3 from a blazer or astro van or any other chevy in 95...the t5 trany should bolt up and the mounts should only need slight modification but with the disributor it opens up posibilities such as a full MSD Blaster ignition and a computer would be needed so a special configured computer would become an option an with a 96+ year engine obd2 becomes easier to install...any thoughts would be appriciated to work out the bugs before i go and blow all my cash

on a 4th gen, you will need a v8 front cross member,v8-90*v6 adapters for the motor mounts( there is a place or 2 to get those at) you will also need the bellhousing from a v8 3rd gen (a 88 up v8 t-5 would probably be better geared for the 4.3 than the 3.4 t-5)
a 96+ 4.3 would be the way to go(the one that the tb points up, has a lower intake manifold and a flat distributer cap that would fit under the 4th gen cowl)
you defanitly want to add a bigger cam and some tuning to the 4.3, or you will end up with less power than a 3800II (175-190 hp on a 4.3) the 4.3 dose have good heads and a large displacement.......

See, this is what doesn't make sense to me.

For exactly the same amount of effort (and cost) and the same components (mounts, bellhousing, etc...) you could be dropping in an older small block chevy. The mount locations are exactly the same, the bellhousing is the same.

You add a crank fired ignition system and a holly throttle body and your off to the races with 2 more cylinders, and a heck of a lot more power than the 4.3.

I think that you should think about this a bit more.

Re: ok...fun swap

Don't get me wrong. I love the 4.3. have been working on the marine version (both OMC and Mercruiser) in my boat and father-in-laws boats for many, many years. Even worked on the old 3.8 90 degree Chevy V6s (in both cars and boats). It's a workhorse and is extremely dependable and durable.

Re: ok...fun swap

whats the standard tranny on a older 350?
how much hp does a older 350 have? I forgot

Re: ok...fun swap

Depends on what year and car removed from.

A 350 pulled from an 86 Z28 would run about 230 HP.

A rebuilt stroker 383 small block (300 HP) is quoted at $3800.00 (CDN$$$) at a parts store in my area.
