You might have to smack it with a dead blow hammer a few times to get a 1/4" more room but thats it, shouldnt cause any noticable damage. Getting rid of the I-4 i see? Had the idea of replacing my 454 with one last year for shock value but they are hard to find, if i were closer and had the money id buy it off of you, good luck withthe v-8 swap and post some pics. Later!
i give it to the dude who rebuilt my new engine it whas a little shoe box but had a lot of power but whas beyond rebuilding options and if i had it i would be glad to give it to you free of charge it had a power glide air cooled trani it whas awsome but not enough power
