I found a thread that I cant find now, but Mark Montalvo made 2 versions of a 421, one was the typical 4.125 x 4.030 and the other was 4 x 4.130 or something huge like that, it HAD to be a sleeved block. Gotta go to dinner now so no more tech for a few hours.

Machining cost, each sleeve is 70+, then I figure at least two days to get it right. if you want to get the high dollar Dartons it well be even more.

I asked my local machine shop about costs just 2 weeks ago. To sleeve 1 cylinder it was $140 a hole, and that is just to install the sleeve and trim the top to deck height. That price didn't include a bore and hone. Maybe they could cut a deal for doing all 8 but it would still be a $1500ish. I'm not sure if it's possible to do all 8 anyways. I didn't ask them if they ever replace every cylinder in a block.

70 is what they cost the shop, it would still cost me at least 750 in materials, my labor isn't included.

*If* you can get away with sleeving all 8 on an 327 block without causing other problems. I'd imagine you're pretty much guaranteed to hit water on an LT1 block, so IMO making it seal will probably be the issue.

Wish there was someone with a lot of LT1 block knowledge to chime in here.

very true....even if you could get another .040 out of it and be able to go 4.100 it would be a huge help in getting a bigger valve in the head.....hell even 4.090 being limited to a 4.060 max sucks lol

Full fill the block, run cooling only through the heads, and run alcohol. You wont overheat. If you do run hot just add fuel.

They have, My last block was sleeved, Just not big cubic inch. Most people dont because of build cost, 427ci will need some nasty heads and intake to make good power. Hell i had 2900 in my last set for my 383, your going to have 5k into a real good set of heads for that cubic inch.

you might be able to get away with it on a strong n/a combo. but i don't think it would hold at my power level. i may run buy the guys on yb and see if any one has done it.

joelster

I asked the guys at the machine shop if they could do all 8. They said they could but nobody ever does. I have heard from "internet lore", that the blocks loses integrity when you do all 8 at once. Not sure what to believe.

I have heard it weakens the block too, but I remember when I was researching seeing an old thread on Speedtalk where a well known SE racer with champions to his name sold a fully sleeved block and said it was done to make the block stronger.

Just another situation where I wish I had unlimited time and money, I'd test all this **** for myself just for ***** and giggles.

I'd love an SB2.2 4.1" LT1 block. 750hp NA or I'd burn it.

Just like like the racers used to do with BBC sleeve all 8. They called it a econovan since the Donovans were so much.

That's so badass, love the raised deck.

No offense but I think its obvious that you might still be in high school or middle school. I would not worry about fantasies and focus on a simple budget build. With your grammar are you passing school? You need to grades to get a good build!!

On to the fantasy: There have been plenty of well built LT1's that have hit over the 1000hp mark. Most of them were smaller then 400ci let alone 427.

Tat correction: THAT
