todd,

how about a "c5r" style crab cross ram intake?

would cost lots of low end torq but a 427 lt5 that power peaks at 7600 might well make 800 hp. dunno, never seen it.

but good to know that 800 hp is available from these heads

wouldn't it take around 400 cfm or so to get there??

and some BIG cams. I don't want to go any bigger on my cams, just like the heads to flow way better than they do now.

I think you may be on to something there.

A solid OHC engine using solid direct acting lifters would be "lashed" via shims.

Yes.
Sorry for the confusion.

Too much hassle, no benefit imo.

todd, what changed?

I'm raising the peak power speed, and using a much more aggressive cam lobe. On top of that, I am really pushing the piston to valve clearance tight, so need absolute control of the valve. Trying for 800 hp.

the guy to talk to about solid cams is fastlane

lane Goldstein he put quite a bit of effort into twisting the lt5 to 9k with his drag car with specialized chains, deck plates, a Hogan style sheet metal intake, and 421 ci producing 900 hp

love watching him drive that car, a shame it sits now

the maintenance to shim that engine and his maintenance routine involved periodic engine pulls and chain replacements

the longer chains were a thing of beauty but lane was pretty on top of the preventative maintenance program and the car performed accordingly!!
