need help asap what carb for my motor 600 750?? edelbrock

thats why i hate holley ive had 10 of them and every one was problems blowing power valves leaking here or there i just never had any luck all ways losing tune
plus i want to run all my factory stuff linkages brackets what ever else
dont want to even have to think about brackets and cabels

If you are blowing power valves it is not the carb fault....you engine is out of tune and backfiring back thru the carb....

and yes...they now have a pv protection...

in the end...it is your money do what you want....
