After having dealt with all the typical swap issues with various other mounts...trying to find headers to fit, driveline angles being wrong, oil pan clearance issues, etc, I started using BRP/Musclerods swap kits and headers (made by Heddman). They are engineered to work together, so there is no guesswork. I don't install anything else in my shop, unless it is an application they don't have a kit for (and they have kits for nearly anything).
I'm a dealer for BRP/Musclerods, and will discount the swap kits to $449 (current retail is $489) plus shipping for Malibu Racing members. Please speciy model and what transmission you are using. For the matching headers, we have :
1 3/4 mid length, coated $479
1 3/4 long tube, coated $649
1 3/4 to 1 7/8 stepped long tube, coated $759
1 7/8 long tube, coated $669
1 7/8 to 2 stepped long tube, coated $799
2" long tube, coated $729
