OK, it started out buying everything for my 455 rebuild at one catalog who said I should use a 270H Comp cam. Heads are 6X-4 converted to bog valve, new ARP studs, Comp 995 springs and roller tip rockers 1.5s. Then, Comp said to send them back the cam it was not right for my engine and sent the XE 268H to me. Now, I am reading in Jim Hands book and looking at other engines where the Comp XE 274H is used alot.
Question: Before I install this new engine I can swap to the XE 274H like I see so much of. Keep the XE 268H I have (No Want A wuss engine) Or buy something else. Also, heads were never ported, just cleaned a little. Pull the heads and send to Spots for port work is an idea also. Engine was going in a first Gen Bird but now a 66 Le Mans. And my point being? Simple, before I install the engine I want a good Cam that will produce enough Vaccumn to supply brake booster. And, sound tough and run strong on a street engine. Carb for now anyway is sitting in a box and is a BG Speed Demon 750, with an RPM Performer Intake, and headers yet to be decided maybe using the RA ones by Company Who makes the nice ones. Or, Maybe DOug's. So Come one ya guy's you've helped for all the other stuf I had questions about. It's sure was a good way to learn that next time I'm ahead having someone good build it from the cround up for me. Nope, I can't do it myself because I'm blind and will be driving the car in really wide open spaces only. But, driving it hard. Thanks, and choices for the best Cam will win my vote and order it in the next few days. I, listen, debate, listen more, and then order now that I have gone through this. By the way, never listen to someone who's a salesman but not a user for the thing's they sell. < Mike >
