i have a c-4... not a c-6. ive had it for quite a while. i know the difference between both. Anyway, im gonna go with a 302. but i found a five 0 today and i might buy it. gonna "test trive" it tomorrow.

 

if the 5.0 checks out , buy it & forget about the 390 swap, unless you are up to a lot of work & headache's , but this is a decission only you can make. you can spend time modifieing that 5.0 & make it faster. good luck.

 

I will go against the grain and say go with the 390. Course I could be biased toward the ole 390s.
