Guys,
I'm currently figuring out the direction I should go regarding upgrading my 351W (M-6007-B351). It's an old GT40, non-roller cam crate engine. I have a set of TFS TW 170's single spring heads, 58cc (TFS-51410002-M58) that I got very cheap (I know these are on the small side but they are way better than iron GT40's) The original cam is a flat tappet cam, .491 valve lift intake, .509 exhaust valve lift. 220 duration intake, 230 exhaust duration. It has a Edelbrock performer RPM, Demon mechanical 750 , with an AOD/3K stall, and 4.10 gears I used to do 12.7 on the motor, 11.7 on the bottle.
Here are my questions:
1) Is this cam a decent match with the heads to the point that I should just leave the cam alone?
2) If I do switch cams Is it worth while switching to a roller cam or avoiding the expense of double valve springs, distributor gear, roller lifters, push rods and just get a new standard hyd cam with more aggressive specs?
3) I currently use 1.7 rocker arms. If I go to a new cam buy 1.6's or stay with the 1.7?
Thanks in advance!
Tim
