Motor specialists- anyone?

I have 1987 TBI 2.8L S-15. Will boring out the '87 block to 92mm and add 3.62" stroke work to get the 3.4L? I belive this is a genII motor right? Do I have the better genII heads. Will the Edelbrock 4bbl intake and adapter fit genII or genIII as well as the headers for a pre-1986 motor? I want to use the HO iron or 3.1 aluminum heads, just use the bigest valves and heart shaped chambered heads (genIII) I can. Any numbers for them?? Is there a difference in the crank bore, I want to keep the 1piece seal and current oilpan w/1 piece gasket. I havent taken this apart, do I have a windage tray and crank scraper?
Would the DOHC need a lot of adaptaion to fit, is there one for a RWD? I can re-program PROM or get the MegasquirtII to make it work. I want to keep cost below $2000. My tranny is built and ready for 400+hp.
Thank you for any response as this is a new motor for me.

1. Can't bore it out that far. The 3.4L blocks have more metal around the bores to allow for the larger bore.

2. You can't use a standard carb intake on alum heads as the port spacing is completely different than the iron heads.

3. Headers for the iron heads also will not work (without some alterations) on aluminum heads due to bolt spacing.

4. Almost 100% sure you don't have a windage tray and I know you don't have a crank scraper stock.

5. There have been a couple people on here to place a DOHC in a RWD config, although not sure the success of any of them (with the exception of Rebel's, but his is a totally custom framed car anyway).

The 3.4L DOHC heads wouldn't work with major modification.. if you wanted something like that you would be better off getting one and trying to adapt it to a RWD. Or just get really smart and get a 3.5 or 3.6 DOHC engine and getting the adapters they made to make the Rendevouz an AWD

If your budget is $2000... you'll be time and money ahead to go buy a small block chevy and bolt it in. It's been done a thousand times... but what you're proposing is a rather interesting and original method of throwing your money away.

No doubt, if its an S-15 be diffrent and put a bigblock in it!!!, my buds dad has a 383 with aluminum heads and a cheater plate in one.. Hauls ass!!! but a bigblock would top it off.Juss Narow a ford9 get a set of stickies and ull be doin wheelies for a block!. Plus you will be well under 2000$ or who cares do a 350 swap and if you ever want to spend more parts are VERY VERY redaly avalibale!!

and you "Can" do such a thing as make an 4bbl intake for the aluminum heads.. but u have to know how to weld aluminum,
One day when they let people run 3 phase in there garges I wanna make a bunch more 4bbl intakes for the aluminum head engines, so peole who wanna swap on those heads to a carburated vehical can.

why can't you run 3 phase in your garage?

[tractorman]

I think what he means is "one day when my Mom lets me run 3-phase into the garage..."

[Ortie666]

Naa my mom fucked off to BC, I live heer with my dad.. They wont let you run 3 phase in your garage because its a residential area, for saftey. We already looked into getting some high voltage comin into the garage for a lathe or a mill.. But what happens with juss the 240v is it always trips the breaker so when Tiging aluminum you can olny do about a 4 inch patch b4 it trips, aluminum is bad for needing alot of power and heat..

[bszopi]

With the right 240v setup, you shouldn't be tripping any breakers... And yeah, I could see it being somewhat of an issue bringing 3ph to a residential area that isn't setup for it.

[Ortie666]

ya, its hard to say, The Arc/Tig welder Likes too trip The onboard one, so it might have to be changed to a higher one.. but the Mig likes to flip the 240v.
