I have a good friend who completed a Brodix build last year for his 70’ Chevelle. It’s a 632” that makes 904 to the tire on pump gas, and well over a grand on race gas. Drives great on the street, and doesn’t overheat.

Thanks Scott! I really like the LS engine, but since this car is a real SS396, it had to have a big block!

Can't wait to see what this monster does. I've heard of some great numbers out of the 509 and other 4" stroke builds over the years so i'm sure this one won't disappoint either.

Those ti intake valves? nice

You have head flow specs you are willing to share? Scott also had my vintage Dart 320 heads so I'd be curious how they compare to the AFRs. I would've liked to have gone with a newer design as well but given I had these and they were practically new I couldn't see not using them.

I can't wait to see what it does either! I have the head flow specs and "good" ports flow just over 400 cfm and the "bad" ports flow just under 400 cfm. Combined with the solid roller that Straub spec'd, it should move some air!

Not much too update other than picking up another piece of the puzzle from Bowler Transmissions. Once I get a bellhousing I’ll be able to mock up the engine and trans location.

Chassis is looking great, Herb. I'm doing a similar set-up on the rear of my '66, but I'm doing mine on a very strict budget and building most of the brackets, etc myself. I'll probably have to enlist Ron's help with the front as it will be a blend of stock mounting points and other GM components. Thanks for sharing all your work pics!

Thanks Ric!

Just a few small updates...

On the engine, I got the cam installed, degreed it (ended up 2* retarded), and checked piston to valve clearance (.120" intake, .160" exhaust). I also installed the rocker stands but I'm going to wait until I get closer to starting the engine before I install the rest of the valve train. No sense putting the valve springs under stress while it sits on the stand.

Next was a big step forward on this project... separating the body from the chassis! Now that this is done, there's no going back!
