Re: 496 vs 511 vs 525
^ The whole idea for me is to have a big block with less torque off the line than a 540/565 that will wind up like a smallblock. Experienced racers all seem to agree that the best engine is one that gets back into it's top power making RPM band after the shift and these short stroke/big bore engines are just the ticket. I ended up with a pair of L88 replacement heads (3401 castings) that I'm having fitted for 11/32" valve stems and ported. If I can get 350cfm or so out of them, that should fit the bill nicely for my project. This isn't a race car, just something to irritate the rich boys with their brand new 700hp store-bought plastic cars.
Organized people are just too lazy to look for their stuff...
