For those who don't know what's going on with my current problem/situation, I've recently been dealing with a lifter that's been making noise ( http://www.chevelles.com/forums/showthread.php?t=193101 ). If the lifter/cam is in deed my problem, then it looks like a new cam/lifter set up will have to be in my near future. I know that I can't just pick out any cam outta the catalogue, so that's why I'm here :) My current set up is a 391ci (daily driven), 9.5:1 C/R, Keith Black Hyperutectic pistons with I believe a 12cc D-dish cup, ported Bowtie heads with 2.02/1.60 valves, .488" I/E cam (have no idea what the rest of the specs are....lost the spec card years ago), Edelbrock RPM intake, Holley 750VS carb, 2" spacer, Hedman 1 3/4" headers, 2 1/2" exhaust with X-pipe, TH350 tranny, B&M Holeshot 2000 converter, 4.11s gears out back. I think that about sums it up :) I'm not really sure what my vavle springs can handle, but I think it's safe to assume that I can't run anything more then a .500" lift cam.
If I had the money, I would LOVE to upgrade my heads to some AFRs, go with a higher stall converter, and a disc brake/hydroboost set up so I wouldn't have to worry about engine vacuum :D
Currently, my set up has run a best of 13.3@102? on the 1/4 mile (sorry, don't remember exactly right now LoL :p ). I'm positive that it should've run at least a 13 flat because my 1/4 mile's 660' time was 3 tenths slower then my 1/8 mile's best at Irwindale (1/8 mile track) was, which is in my sig. :)
So yeah, I would deeply appreciate any and all help you guys can give me! :) I would LOVE to go with a cam above a .500" lift, but I know I would have to have stronger valve springs (which in reality, I would just be better off going with aftermarket heads), and make sure the valves would clear the pistons, along with making sure the cam provides enough vacuum to allow me to use my power brake (drum) set up. I do remember reading somewhere that a cam above .500" lift CAN be used with power brakes, but I believe the duration would have to be shorter (or something like that), to work properly :) Thanks! :beers:
Edit: I have NO problem going with a higher stall torque converter...just an FYI! LoL :D Oh yeah, and if at all possible, I would like to improve my car's ets with a better cam...if possible :)
