straight six to v-8

I have an 86 fullsize with the straight 6 motor and the 4-speed manual but am going to swap in a 351w. any forseeable problems? motor mounts, starter, flywheel & clutch, bellhousing and the stupid ignition unit. I will probably go find a decent junker and build it while my 6 just leaks all over the place! thanks for the help guys!

Re: straight six to v-8

starter clutch bellhousing, transmission are all the same. not sure about flywheel. Did you think about converting to fuel injection on the six, or going four barel manifold? the injected 88 motor has like 285 lb ft of torque at 1600 rpm. i like my new fuel injected 302, but still miss the old one barrel straight six in my old bronco. damn, i knew i shoulda kept that motor when i wrecked the truck.

Re: straight six to v-8

I would rebuild the 6, especially with the 4 will have better torque w/ the 6...clifford performance has most anything you need to get more bite...I put a 4 barrel with a offy intake and headers....I like it... your fuel mpg should be great with 4 speed...

To make the swap worthwile, get an EFI. You know you want one anyway [img]/wwwthreads_images/icons/smile.gif[/img]. Mileage, diagnosis, parts availability, upgrades, performance & driveability on- & off-road, durability, etc. I went from the 1-barrel ring rinser to EFI and I've never looked back (except the occasional "I could've had a V-8!" [img]/wwwthreads_images/icons/wink.gif[/img]) I'll never rebuild another carb'ed engine.
