I installed a 350 4 bolt crate engine im my 1986 C20 three years ago then pulled it and replaced it with a 454 I then installed TBI on the 350 and installed it in my 1951 3100 along with a 700R and it is the best way to go. Ive had no problems with it towing my 25 ft. 7500 lb fifthwheel AND now it going to rip up the streets in my 51 !!
GO WITH THE CRATE ENGINE
Just like Bob said "like a rock"

Some people are like Slinkies, Their not really good for nothing... But they still bring a smile to your face when you push them down the stairs.
