Heres the pics i promissed. Ill try to explain them abit. the first pics are of the Flaming River steering column im gonna use. With my AlterKtion, i ordered a plate that would move my column over a touch to clear the rear of the hemis wide heads. Well, im happy to say the plate worked out great as you can see in the first pic. Youll see it doesnt touch at all. The following pics after this show how the u-joint will (with some trimming of the heatshield), clear the exhaust manifolds. Now someone might ask "why not just get ride of the heatshields altogether", well i want to keep them on if i can. As ive stated in other posts, i want my enginebay to have a factory feel about it. Also heatshields on exhaust manifolds help reduce some heat in the enginebay and personally i think they look nice.
As far as headers, I believe headers may be out of the question if your gonna use a stock K-member, however, with the alterktion youll have room.
I gotta say Bill at RMS has made this hemi swap thing alot easier on me. remember this is an Early Dart (64) so the new hemi is even tighter in the engine bay then in 67 and Ups, so if your gonna use the alterktion youll even have more room then in a early a-body.
I cant say for sure if a 5.7 hemi would clear in an Early A with out using Bills setup, but i know it will fit in a 67 and Up, but you have to use manual steering, use a remote oil pump, and TTI headers.
