BBR's 83GT - 552 BBF version 3.0 (at least)

[STINEY]

Holy crap. I didn't believe it...........that paint really is toast!

That's some pretty serious destruction just this side of total disaster. I'm 3rding the motion of stockish 460 and a turbo, cheapest path to same level of fun with better manners.

Been really thinking A LOT about turbochargers lately and the current engine package is not conducive to adding any sort of forced induction. Static compression is just too high and it would need a huge turbo to work properly. Plus 10.00 is as quick as I really need to go and a turbo'd 545 would have the potential to eclipse that by a significant margin. If I wanted to turbo something, an S480 blowing a stock bottom end 460 (10-12 psi) or a stock 5.7L Hemi would probably make enough power to run mid/low-10's up here and still be plenty mild mannered on the street.

Anyway, that's where I'm at.

My eventual Cadillac plan is a 472 or 500 with mild'ish compression, a low'ish lift "gas mileage RV" cam, and a turbo. See if I could pull some decent mpg's with an over drive or highway gears and then boost my way to HP when I need it. The low end torque with the cam shouldn't have any problem getting the car moving while the turbo is spooling. Its just a napkin plan at the moment for me.

How about keep it a 545, with lower static compression, milder cam, and a turbo?
How horrible would the stock iron heads choke the 545 with a turbo?

I like the idea of using the block from the JY EFI engine for the car, and the EFI stuff for the truck. (stock computer or megasquirt?)

It seems those heads will take a good bit of work to be usable again, and they might have to be milled - further aggravating the compression issue.... too much machine shop time and you're better off getting another set. You could run the iron JY heads for a season, then swap heads later?

Stock heads with a turbo on a 545 would be crazy. They would probably tap out at 3500 rpm. lol

I currently have an email in to Probe about 2 pistons and a buddy is checking with his machine-shop owning Dad about a block or a sleeve.

A JY set of heads (like the D3's I have sitting in the garage) use pedestal rockers. So I would have to have them converted to stud rockers or something.

It's tough to decide what to do. It's been such a fun, fast combo, I kinda hate to change it up but there's a part of me that want's to do something different too!

[Beagle]

The E6 fuelie heads use completely different manifolds, both sides... Scotty could port them up for an EFI 545 in the truck that would probably be a riot?

[BBR]

Yeah, but for that kind of money, I could probably buy a new bare head, and be on my merry way. haha

pics of the dent in the cylinder wall? I had a little dent in my 454 when it dropped a valve, I just ignored it.

[BBR]

Only pic I have of it right now. About 3/4" down and the depth gauge on my calipers shows 0.030" deep.

I'd be more concerned about the gouge at the top.
My vote is the smallest ci you can find that can get it to 10s (with a turbo.)

Bright side, it totally looks like you can save the spark plug from that hole!

You want him to put a 4G63 or a 'busa motor in it?

Negative. That plug was totally bashed. I put in a new one to keep the rain out of the engine.

Cost wise, it seems like the "fix it like it is" is possibly going to be the most cost effective.

To put it back like it was, less head repair cost because I want to use these heads regardless of what short block I use.

2 new pistons = 225
Sleeve = 125
Rings = 112
Rod bearings = 75
------------------------------
Total 537 (roughly)

Wrecking yard engine:
EFI 460 = 500
Camshaft = 125
Lifters = 50
Pushrods = 75
Valve springs = 100
-----------------------------
Total 850 (roughly)

So the question - what do you want the car to be? Is there more in it? Are you going bracket race it? To me, I do cars because I like learning new things in a hands-on approach - so I'd take the money and run to something new and/or exciting. While yes, you could fix the motor, you don't have to put it back in - fix it and sell it could also be an option to fund something you've been considering.... I like the hemi/turbo idea (fwiw)

[BBR]

I was pretty fond of it like it was. lol I am leaning towards getting it back to where it was, and then begin collecting parts for the next phase. I will be building a shop next year, so fixing what I have fits that timeline better.

[TheSilverBuick]

A shop eh? The driveway ornament has finally overstayed its welcome?

[squirrel]

shop is good. Although it takes time and money from the car in the short run, it lets you have more fun in the long run
