Thread: toss up for a motor in my 54, need your help

Re: toss up for a motor in my 54, need your help hey guys. Had a couple high hp low weight cars. Had a 2200lb vw jetta over 500whp. Ran 11.2 1/4 spinning first on a 22"slick. 2.1 60". With the right slicks and the right engine mgmt car would have done mid 10's. Also had a vw rabbit with 300whp (1800lbs). Dont get me wrong I like the vette, but for the money and the NAME I was expecting more. The most memorable american...

I know the 67-72 C-10 guys have to change out the oil pans to get them to fit.

The LS1 is the best bang for the buck. Power, reliability, and great mpg for the power. The aluminum block LS motor's are fine. I've never heard of a main bolt coming out.

Good luck on the build and keep us posted.

Stay away from the early LS1's with aluminum block. My machinist tells me that they had a problem with some of the main bolts pulling out. I think thats why they went back to cast iron for trucks. AHh I envy your amazing deal! I picked up a 2001 5.3 with all the...
