anyone have any experience or knowledge about edelbrocks new RPM xt heads cnc'd heads ................ how do they stack up against afr 185's for a 347
For the record, that car in the article has gone quicker as of lately.
I believe he's at 11.0 or 11.1.
I'd expect him to get in the 10's, since his other naturally aspirated 347 car he owns goes like 10.50, but that's an R block with solid lifters and jesel rockers.
