My points is yes you can get a V8 s10 to pass emissions tests,no I disagree with the costs of a V8 swap costs being as high as quoted,and more on topic,I do think you can get a 4.3 to run a output of 300 HP.All your asking for is 1.14 hp/c.i.

No argument from me. The point I want to make to the OP is there are better ways to spend money, unless all he wants is to run some number for bragging rights.

If he's serious about making power and going fast at the track, the V8 swap is a logical solution to using a ~/<265 cid V6.

Otherwise, buy a better platform from the get-go. A truck is cool, but it's never going to run the same mph as a slipperier vehicle w/the same power.

Hey Cobalt.You said the V6 OEM heads don't flow.I know the early versions had some issues,but the later Vortecs where much better.I'm curious if there is something I'm missing.

If your going to race please take it to the track it's not worth you dying or killing someone and ending up in jail if you street race.

My brother had a S-10 with a LS engine in it he would race it at the track it was a blast. Be safe buddy I see your young ok I care about you well I care for all.

I had a friend in high school with an S10 (didn't most of us have one of those friends in high school if we're under 40?). We tried Marine heads, Marine intakes, ported heads. We got started on an M90 conversion, scrapped that for a turbo and scrapped that after getting half the front end torn off to get the piping mocked up. Rich then tried his hand at porting the heads, and after 40hrs and 2 sets of heads...was no better off. Building a 4.3 to run 128mph can be done; but if you don't want to run the risk of being let down in terms of eating your budget, or marginal performance you may want to think twice.

Heres what I know. When I was your age, I had the money to do something once. So don't take what these guys are saying as a slam, its not. We want successful hotrodders. Also, the first thing you'll do after running 128mph is want to run 135. This is one of those laws of hot rodding.

Now after giving no hard information, heres some technical info.

You could put a stock LT1 in there and it would be cooler and more legal than a carb V8. It'd also have more room to grow than your maxed out 6'er. You can find a good running LT1 for less than a grand. You'll probably have to build a swap harness, but its not impossible, and there are several good how-to's on youtube for these kinds of things.
You'll also need to look at your trucks fuel requirements for this kind of power, I bet due to its age, it's marginal at best by now.
Personal experience; Im a member of the 3rd Gen camaro/firebird forums. There are a ton of guys over there who play with the 6 bangers and have a wealth of info. Most of em that dump money into them, come up short and kill the resale value of their daily driver. The smartest ones build a 2nd powerplant, and swap it in over a week in order to minimize down time. And then sell the car and buy a V8 one


You really want to do it? 3.23 gears and a bucket of nitrous oxide. This may or may not be legal in your area, and you'll probably run the TBI lean and melt it down. FYI a full bottle of nawss in your car is not legal in most areas, armed or not. As a young guy, they'll be itching to throw the book at you. Most of us here have 1st hand experience in that.

Stick around here, you'll be an asset for sure

his location says florida. maybe he wants to be able to run with the flow of traffic on I-95?

[Turbonoma]

Wow! haven't been here in ages. Still have my truck and drive it every once in a blue moon. Have drifted to many other hobbies.

I own a shop truck 4.3 1999 Sonoma 5 speed.I know to change plugs on that is a real bear on number three plug by the steering shaft.I just can't imagine what it would be like on your turbo set-up.BTW-very,very,nice work on that mod.Very impressive.

I change all of them through the fender wells, take the tires off and its a MUCH quicker and easier job.

[vinniekq2]

I dont change them at all.I have 2 young mechanics with shiny tools that like to do that...lol

[1Gary]

Yeah through the fender well for sure.The recommendation is to drop off the steering shaft and I don't wanta go through all that.I was told Snap-on sold a special socket,but when I asked him about that,he didn't know what I was talking about.
