You'll have to drill the intake for your distributor, figure out some sort of distibutorless ignition, or figure how to install an optispark. I wouldn't go that route though. Even the MSD opti's aren't as good as a tried and true HEI.I might have the facts wrong from the seller. He told me the top end came off of a lt1 powered caprice cop car. It uses the optispark up front that is driven off the waterpump? He has everything but the block something about it being busted. I've got a good 30 over one piece seal block I would like to put these heads and intake set up on if they will work and cool right.
quiestion for you, will those heads work with a 87+ head bolt pattern? where the two center runner bolts are a different angle? like 74deg instead of 90 or what ever?does any one here know if the lt1 heads will bolt onto the 86 and up 1peice seal block? I can pick up a set pretty cheap plus it comes with the fuel system.
so the heads will bolt to the block, got to drill and make mounting pad for distributor. Now the heads get cooling in the rear on a crossover first? Will the stock lt1 cam have a drive gear for the distributor? I thank you guys for the help.
But if you use a TBI distributor it has it's own pickup inside. Could be worth trying.oh ok... they're just running an HEI, but still using the opti to feed the computer the high and low resolution signals.
bascially... they're doing the same thing as the delteq. they're just taking the high voltage out of the opti, but still using the optical side of it.
the original poster is still SOL with all of these, because he has a regular SBC shortblock, which can't run an opti.
