4 bolt lt1?

[my95z28]

Like I stated, I don't BELIEVE that it is possible to angle the two inner bolts, therefore if you take in a 2 bolt block, and say I want splayed mains, I think it comes out looking like this




Where does it say that on Summit? Can you link me?

[Caveman]

alright i got it now.. sorry i wasnt quite tracking right away.. i thought a splayed cap all four bolts were angled.. but thats great thats not the case..
and i was f'ed up again...they have two bolt caps but they arnt splayed..only 4 bolt caps are splayed.. your right again kyle..

so now that i think i found some caps... (http://www.summitracing.com/parts/ES...S/?image=large)

where can i get the block work done? bout how much do you guys think it will run me? dont wanna cry too much when the guy gives me a price..

my 97 is a splayed 4 bolt, was stock 2 bolt. the bolts are angled because its harder to pull out the angled bolt. and they dont flex as much, so a splayed 4 bolt main cap is stronger by far than a stock style 4 bolt main. but the rumor of fbodies with stock 4 bolts is true. my 1st SS came stock with a 4 bolt, when we pulled the motor the 1st time i about shit when i seen it was a 4 bolt main i actualy have a 4 bolt main LT1 block chilling in the garage

I had good success with State Motor on Gratiot in Eastpointe. It's right across from a dealership just south of I-696. Can't remember what the dealership is/was... not sure if it's still open either... Mike Reihls or something like that?

[my95z28]

Lol, no biggie Dave, its hard to convey things thru the internet sometimes. I honestly have no idea on the price, maybe Don can chime in how much he paid?

Its not too bad, got a quote to do the motor in my Z for 200 i think

[JoeliusZ28]

wow thats not bad.... gonna have to do that to mine eventually then.

thanks for the informative thread! i woulda done this research on my own but i had class all day.

[Lucky SOB]

well i just learned a lot. 200 doesn't seem bad at all.

If you can get it done for 200 go for it

Performance Eng. where I take my stuff gets 360 to do it.

If you can get it done for $200 by all means go for it.

I talked to my machine shop about doin it to my block and they said:

1.) It was TOTALLY unnecessary for what I was doing
2.) It would cost a LOT, $350 to install the caps, $200 for an align bore, the cost of the caps, and ARP studs for the caps

So I left the 2 bolt mains with a good align bore and ARP studs and have been spinning to 7000 with no issues (knock on wood )

Stock 2 bolt should take up to 500 hp.

Stock 2 bolt should take up to 500 hp.

well, thats supposedly when the caps will let go. Id be more concerned about the stability... an unstable cap will cause premature wear on the bearings, meaning the 2-bolt will probably spin first if you are spinning very high RPMs with less than 500 horse.
