340 replacement block.. with a roller cam?

hrmmm... care to elaborate on that? Id really like to take a 59-degree route with a 340 replacement block, but a roller cam seems the way to go for performance, and Im looking into a street/strip dealy. Something to take to shows, but be able to put the rubber to the ground and run mid to low 10s at the track. 48 degree blocks are a pain to build considering special cams, heads, etc. Id be doing drag, but was also considering doing something to the effect of circuit racing? not sure what to call it, F-1 but not so fast? :D its what my bro plans to do with his 64 and a half mustang, and I thought it would be cool to, so yeah, not sure as of yet, any suggestions? was considering a stroker, 418 ci with a 340 replacement block .040 over, with a 4" stroker crank, but then I get concerned about not being able to run high revs, which is kinda natural with the whole circuit racing deal, is a 48 degree worth the pain? with a procharger or something to the effect of that? high revs but you can still keep the power? 7500 would probably be the limit anyhow. Poor pushrod geometry is killin me here :P appreciate any help, and any comments if anyone has done this, or the circuit racin deal
P.S.> the build would be a 63-67 A-body most likely(65' Dart GT hardtop is my interest)

It's when the valve lift becomes really high (combined with extended high rpm) that you see problems with the 59* tappets. I use a .640 lift solid roller and i turn the motor 7800 - 8000 rpm with no problems on the local dirt track here in fairbanks.

And with a longer stroked motor you can build your motor around the cubic inches. With a good 410 - 416 - 418 you should be able to keep the rpms well under 7500 and make plenty of power.

And to the OP, comp cams have come out with a solid roller tappet set made specially for the new 340 replacement blocks.
