I have noticed that a lot of guys have changed over to HEI and have seen benefits of the swap. A couple days ago my dad bought a car with a spare 70's chevy 6 cylinder. I have read that you want this era of distributor, so i took it out of the engine and here i am. My question is what is involved in doing the swap, is it just a matter of changing the drive gear off the toyota and the drive gear on the chevy? Thanks, Dylan
