perfect reply!!! i traded an exhaust system to guy who pulled this out of his monster truck when he parted it out. and dressed it to look decent, and old. i woulda traded for hemi but couldnt find any takers! haha.. after putting about 40k miles on it it still would smoke just about anyone thet tried me.. it would be a cold day in hell when i wrapped up 5 grand in a flathead that this sbc would KILL!! hot rods should be fast... also liked to know that when i was 6-10 hours from home and something broke i could get parts. worste case scenario if i blew the damn motor i would get a ride home and get another one out from under the bench and go back with my truck and change it out alot cheaper than the cost of the tow!!!
