RE: [Chevelle-List] Header installation

[Craig Ellis]

Bill,   Thanks very much for the help. I've got one more question for you about the 2" vs 1 and 3/4. My engine is a 402 bored to 414ci. The heads are Edelbrock Performer RPM. Comp Cam Xtreme Energy with 552/555 lift and 230/236 duration @ 50. Lobe sep is 110. Domed pistons milled to give 9:7 to 1. Stick shift Muncie, Performer RPM intake with a matching carb. Would you still go 1 and 3/4 or would the 2" produce better results overall?   I hate to bug you but, since I have both sets of headers, I'm keen for input on what to do. I've got to make a decision Saturday. The car is nice but I drive it alot. I also take it to the strip monthly and thrash it pretty good. I just don't know which ones will give the best results.   Thanks -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]On Behalf Of Bill Vander Werf Sent: Thursday, June 12, 2003 7:28 PM To: [EMAIL PROTECTED] Subject: RE: [Chevelle-List] Header installation You can get the supercomps in from underneath if you remove the oil filter and take the bolt out of the motor mounts. Then you have to lift the motor up several inches with a cherry picker. If you can get hold of the motor low enough you can do it with the hood on. I installed the headers with the motor out but I have had to remove them a time or two. I have the 2� ceramic coated version and by laying a towel on the frame and control arm bolts I have been able to install them more than once without scratching them.   As far as your question about header size; I would use the 1 �� setup for the street, even with a mild 454. If the car is to live at the drag strip, as mine does, I would, and did use the 2�. Again, that depends on your cubic inches. The bigger the motor, the bigger the pipe.   Bill Vander Werf   -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Craig Ellis Sent: Thursday, June 12, 2003 7:07 PM To: [EMAIL PROTECTED] Subject: RE: [Chevelle-List] Header installation   Jeff,   Yeah, it's looking that way for me too. BTW, what displacement are you running with those Supercomps? A couple of buddies of mine are telling me that 2" headers are way too big - should be 1 and 3/4. Since I have a set of each, I'm really wondering which one's to go with.   Craig -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]On Behalf Of Jeff Wysocki Sent: Wednesday, June 11, 2003 5:16 PM To: [EMAIL PROTECTED] Subject: Re: [Chevelle-List] Header installation I installed a set of Hooker Header Supercomp headers, and the only way to get them in on the drivers side was to loosen motor mounts and lift the motor up about 2 inches and slide them from the bottom up into the engine compartment.    Jeff Wysocki Brownstown Twp., Michigan 1970 Chevelle SS 1968 Chevelle
