I'm responding to the NG 'cause I've got a review for the Chevy V-8 conversion headers I got from 4WD Hardware and some of the other conversion items. This was a Chevy V-8 w/TPI conversion into a '76 Jeep CJ-7. It'll carry over to a wide year range & some of it's no big secret but thought I'd give opinions for both novice and pro. First, I think the headers were the Hedman in-frame headers w/ball-style collectors (#14300B @ $160/pr) They fit great and the ball collector made exhaust easy. I backed 'em up with simple pipes to two ordinary mufflers and hangers with short turn-downs somewhere around the back seat. The major problem with 'em's the #5 & 7 primary tubes are so tight to the #5 spark plug that it destroyed the #5 plug wire in a day. I got new wires and an asbestos boot (6" sleeve) for that wire. Wrapping the plug with a little reflective/asbestos under the wire would be ideal but mine hasn't burned out yet... The fenderwell headers look very roomy at the primary exit from the heads but couldn't use 'em 'cause I have large, fabricated nerf bars welded to plates on the frame. Not sure but I think any fair set of "block hugger" or "tight tubes" headers would've been better than the "conversion" set and I could've installed the O2 sensor closer to the heads. (Does anybody know?) If I had to do it again, I'd've invested another $140 to get a set with thermal coating. I used the bolt-in motor mounts (#4300 from 4WD Hardware). Didn't want to use the weld-in types out of concern that I'd weaken the frame unnecessarily. What can I say? I wish everything worked as smoothly as these mounts. Went right in using the original bolt holes in the frame and have different hole patterns so you can lift or drop the engine and search for the best angle for the transmission. Work great and look better. That's it for now. Wish I could say that fabricating an intake system wasn't a nightmare and that I don't have a three foot radiator hose in a loop just to fit. P.S. If anyone knows how I can make a speed sensor for my Dana300 and opinions for a programmable speedo, I'd appreciate it. Best Regards, Drink Looking good. I hope you can use those headers.
Thanks, and Happy New Year!
