Hi
I have a 1990 sierra with a pinto SOHC engine in it. Ive heard you can do a lot to tune them up but i dont want to lose reliabilty as i drive the car daily. I dont want to put twin webbers on it but is there another carb i can put on to increase performance? also whats the best cam to put in it, and do the performance exhaust manifolds make much difference?
id be greatful for any suggestions.
Thanks
