69 camaro running in the 10s

I know Burtonsville Machine.

Just found another round at the Dutch Classic race. Look at the wheelstand here. 10.58 on the brakes. Both cars ran too quick by one. Wow. Great eye candy for Stock Eliminator.

Well i tore down the ram jet 502,what a big bore ,ive decided im gonna build that for my car,i dont want to run the fuel injection unit i want to run a nice intake and carb,its an older 502 looks like 2000 build,from arizona speed and marine,the bore is 4.5 inches and the stroke is 4 inches, could i put a 4.25 crank in this engine,the heads look pretty nice alum 12363391,the rods are pressed in,i have it all torn down, every thing looks realy good,the pistons dont have a part number on them but they look low compression,what i was thinken is higher compression bigger cam and a 4.25 crank,any advice would be greatly appreciated Thanks again kris...

You have the makings of a great combination there. Eagle makes a 4.25 Stroke crankshaft that will go right in that Gen 6 block. You'll have yourself 540 CID. Eagle also makes complete Crankshaft Reciprocating Assemblie that will include a forged crankshaft, H-Beam rods, and either high or low compression pistons. I'd also slide in a mild streetable solid Roller camshaft too (NOT a hydraulic roller!) and you will have one bad-ass motor that will have very little or no equal to whatever pulls alongside you!

You can actually slide a 4.500" crank in there with a little extra work and a few extra $$$...with a 4.500 bore you've got 572".

At that point traction becomes a rather serious issue...

I've owned & fooled around with these big engines quite a bit and I've built 540 CID's based on GM Gen 6 502 blocks and you can get a 4.25 stroke crankshaft for less than $800. A 4.500 Stroke crank starts to get pretty expensive. Plus, I've NEVER seen or heard of anybody making a 572 from a short deck block such as the 502 CID. I'm sure it can be done with terribly short connecting rods in that short deck height block but it's really just not a good idea. Even on GM's very own 572 Crate motor, they avoided that 4.500 stroke crank shaft and chose to only go with a 4.375 stroke in a Tall deck block. 540 CID short deck engines have become immensely popular and represent the best bang for the buck.
