intake exaust
.200 141 107
.300 201 145
.400 249 178
.500 279 189
.600 286 201
.700 292 211


i know flow numbers dont mean anything. but i dont know whats good either.
im going to call bret monday to see about a cam just wanted to get an idea on if these heads look like they will cut it.

Considering that many different flow benches (and types) show different numbers... and like you mentioned, flow numbers aren't everything.........but on an adverage bench at 28inches of water(and if no pipes or shady tactics were used on the bench).....those are pretty healthy numbers for a factory casting LT1 head and they should make good power .................Joe

I'd say those are pretty good numbers for a stock casting too. I'm a little suprised that they flow that well on the exhaust side. You'll want to keep that in mind when you pick out your cam... I'm not sure what route you're going, but you may be better off without the big split in duration that you normally see on an LT1...

Dem sum perty healthy numbers for a ltx casting.. we should have another Ltx car that'll move out soon after bret get's his cam spec'd out...

who did the work on these?

my96z

real nice!

i believe that should be around LE2 territory if that makes u feel any better

SS MPSTR

and what exactly is LE2 territory? I'm curious.

reamo04

actually, LE2 are 275/190
LE3 are 280/195
given, those are probably underrated

Colin91Z

I don't see where he ever said that these are a stock casting

So who ported these? And what castings are they?

Denny McLain

Have to agree there isn't any detail. Just what are the details?? chamber size, intake size...........brand??

Decent overall numbers but 211 @ .700 doesn't look like normal LT1 heads.

Most of the contiguous 48 and a few in Hawaii.

SS MPSTR

that was profoundly helpful - thanks.

Lloyd Elliot ports cylinder heads into different specs, he has packaged them by output from the LE1 to LE3 for the LT1. An LE2 Head/Cam package is a $1700ish job.

Then again, like the others said are these the stock castings?

This thread was made over a month ago. If you do a search on the original poster's post history, you'll see he's been here quite frequently since then. That being said, the fact that he hasn't even attempted to answer anybody's questions and offer more details says something.
