Lance, I really kind of hate the idea of not having a FE in my Cobra, either Ponds block and heads, or those from BBM, but I want high TQ mainly, but for the high numbers of performance and for the price, your 514/572 is a great option !
Looking at your dyno sheet, not only is the TQ & HP numbers at even the lower rpm's, but the fast even pulls, are up to 6100 rpm ! Amazing curves !
The only surprise with the 524, was the lower compression of 10:1 ?
With both cid's, what type of cam and numbers are they ?
I'm used to adjusting lash on the sprint car's solid roller and the flat tappet on my 428FE, so either is fine. (there's nothing short of a solid roller cam 360/410 sprint car engine sound, .......except for a top fuel motor) lol.......
How do you feel about solid rollers on the street, even with the isky lifters, valve train and oiling mods ?
Will they hold up on the street under so much idling ?
Kevin
PS- (are you sure the dyno sheets graph of the curve,.......isn't really the space shuttle's) ? Hum.....
