hi there i need some advice.
I go some extra cash and would like to know which is a better upgrade?
change carby (if so which_Edelbrock or holley)
Upgrade to 351 and keep the t/q
Heres my current setup: 302c, 2v heads, all stck with Xb(i think) Spreadbore manifold with Thermoquad Carby( in very good condition and works perfectly).
I like the economy of the spreadbore, as long as i keep the secondaries closed, but also want the performance if driving wot.
