First in advance I am new to this forum and appreciate all the wealth of information I am finding. I have recently purchased a 86 T/A LG4 . the person before me installed a holley 650 DP with the stock distributor and as you all know you can never get it tuned correctly. I am wanting to change to a HEI dist but as I search the different websights such as accel,mallory and MSD they don't appear to offer one for my application. What is everyone else running for carbed setups? Sorry if there is a post on this but I looked and couldn't find anything specific.

 

you will want to use a vacume advance HEI if you are not using the "CCC" ECM controlled carb/distributor setup-vacume advance HEI was stock on '75-80 SBC cars and pickups from ~1975-85. The stock centrifugal advance curve on these "smog era"original applications may not be optimal for performance,but modifying the centrifugal advance is easy.

 

Thanks "8t2" I found one on ROCKAUTO but was made by "cardone" but I was looking for a better quality one. So you feel if I search for one on MSD's website for those years that I could use one of those?
