Well I finally got a cam and lifters ordered for my truck. Cam #
12366543 from a crate 502. My question is will this work with the stock 454 in my truck? Truck spec.'s are as follows1996 GMC 2500HD with a Gen VI Vortec 7.4L (454), Automatic, 2wd. Mostly a daily driver. Hauling 2400lb loads about 3 times a month.
The cam spec.'s are as follows. 224/234 dur. @.050, Lift 0.527/0.544 with a 110=BA LCA.
Any Thoughts?! The questions going through my head are.
1=2E) Will I need to change anything other than the timing chain set and distributor gear? (211,105 miles on the motor now!) 2=2E) Will this cam idle OK or is the computor on the SFI going to give me grief? 3=2E) Is there any other things I should look out for? (Valve spring issues, Etc.)As of yet the motor is still being used. It's not slated to go to the shop till next month. But in an effor to keep the cost down I've been getting the parts online instead of dealer prices! And the wife is starting to question if I can just live with the noise it's making instead of putting more dollars into a truck I JUST paid off! (A bad oil pump chewed up the distributor gear. Replaced but the noise only went away temporarily so the idea came in the cam gear was chewed up to! So I'm replacing both this time!)
Any ideas would be greatly appreciated since the dealers don't even want to speculate! Thanks Dave
