HoOdRaT 3.0..... Blown 421 LSX.

[LRI]

The short block was zipped up over the weekend. The top end comes next.

Were hoping to rattle dust out of the ceiling tiles soon.

I see you went with a belt over a chain.

What were the major 'pro's .. besides vibration dampening

One is the ability to make easier changes to cam timing.

Looking good Chad

Sorry if I missed it elsewhere, what’s this going in/ what’s the details on it?

Can you handle the power of a v8?

 

[The D]

Moar race car things! Pretty please

 

[thejeep]

Speaking of car stuff. My kid and I were watching the Terminator the other night. I asked him what vehicle he wanted (he's 10). He said dad a jeep on leaf springs. And Id try like hell to put a v8 in it. I was so happy.

I'm eagerly awaiting the first claim that this will overheat because the block color will reflect all the heat back into the engine

Props on the bold color choice. I caught a bit of shit from a buddy for painting my latest build the usual Chevy Engine Red instead of something more unique, and he's right.

I thought the gold leaf insulated the block from the header heat?

Gawldang boy you putting that in an Oldsmobile?!

What pan/oiling setup is that?

LRI runs a late model bodied Goat with a dry sump!

I had no part in this. My engine builder likes to mess with me at any opportunity.

Early, mid 1990s. I'm in the Marines and I whore myself to any race engine shop within a half hour of Camp Pendleton.

Richard Conley Race Engines was located in Escondido back then and contracted with the Chapparone brothers (Chapparone Auto Body in San Diego) He was in charge of their engine program for Comp Eliminator. The hope was they'd jump to ProStock but it never happened. Jesel Belt Drives were always used on those things and the rpm they ran (and survived) at was absurd. (##### rpm figures on 18* heads in the 1990s was not very common)

The ability to swap a cam out in minutes was always a plus because they were changed often. Schneider Race Cams was a short drive away it wasn't uncommon to run a pile of them during an all-night dyno session. It was also discovered that a belt drive will produce around a 30hp gain over a typical roller chain. The cam in this new engine is over .800" lift so anything that'll soften the abuse a bit can't hurt.

Running a drive like this means a dry sump or an external wet sump for oiling. The cover for the drive unit lives right where the OEM oil pump used to go. So, there's a 4 stage Peterson pump to go with all of this too. The car is an 05 GTO. Because of how Holden/Pontiac did the steering rack, it limits choices on oil pans. I tried like hell to find one I could buy but no luck.

Get out the software and fire up a spindle. I made the pan from a piece of plate stock last winter. Right now it's all "bright ideas and bullshit." It has not been tested in any way so we all have our fingers crossed...

The engine builder is fitting up the "huffer drive" and the reluctor wheel for the crank trigger now. I made this pulley a year or so ago for the old engine.

This is one he had kicking around. Were running an 8 magnet version as it has a little better resolution.

What brand of crank is that? Did you/your builder do the rod end work? We did alot of shaping on the counterweights to help the scraper out and cut some windage. It also removed the amount of weight we reduced the rod assembly to before final balance of the crank.

Crank is a billet piece from Callies. The profiling of the counterweights is from them.

The rods are aluminum and from GRP. The stroke of the crank and the size of the AL rods required a bit of blockwork to clear the caps. We went with the largest base circle that we could on the camshaft. That and the size of the lobes resulted in some work on the caps of the rods also. This thing is 10 lbs of shit stuffed in a 5 lb box.
