Which brand AFR guage do I need to buy to get my 383 weiand 671 blower 2-750 holley's tuned up ? Does the edlebrock one have the heated 02 sensor , and I guess I need someone too weld coupling in the header for 02 sensor ? What oil do you guy's recommend for my blower motor , it is very hot and humid in houston,Tx . I was told I should not use synthetic
Can anyone explain ! Thanks for any advise .
