I may have to dig it out and resurrect this gem. Unfortunately I don’t know whose car. Block has 4 sleeves so could tell some stories. Both valve seats ground into block.

Come on Tony . . . bring the ole' girl back to life! Now, with a bigger cam in it (like a .500+ lift roller), it could be something.

But, you'll have to bore out the first two cam bearing bores and use some big bearings.

You may also need a girdle . . . and a blower . . . and a hat injector! LOL

Then, a custom 4.375 stroke billet crank and a set of Carillo rods . . .

Now we're talking!

I'm just trying to spend all your money from afar! LOL

You guys are going way over board. Don't need any where's near all that stuff to make HP and a lotta speed Under 300 inches can be very powerful even with gasoline

Ronnieroadster as I said I purchased this engine from a Bonneville racer in LA. 25+ years ago when shipping was cheaper. An interesting old gem that I owe it to it to get her back running. Has. C4 trans I believe I will switch it back to a flywheel. No idea what I may do with it when running.
