hey guys i had the crazy idea to take a 400sbc and just bolt a lt1 intake/fuelrails in it and keep it fuel injected.

after doing some research i saw that it will not work due to the distributor hole not being it the lt1 intake. so here is my crazy thought. why couldnt i use a lt1 cam use a lt1 timeing cover and just block the water pump drive like if i ran a electric water pump on a lt1, and just use the opti with the lt1 harness?
this would go in a 95 z28.

is this at all possible ? h*ll i dont even know if i could wire it up to get and spark from the opti spark haha

thanks Dustyn

 

It's possible to put LT1 heads/intake on an older small block but why? The heads are decent but not really worth the cost to convert them because of the smaller intake ports. Your other idea of putting an LT1 timing cover on an older motor won't work as the front of the blocks are quite different.

 

okay i didnt think about the different bolt pattern on the timing cover. i wasnt going to use lt1 heads just convert the intake to fit sbc heads.

thanks

 

TPIS makes a gen 1 intake that is basically a LT1 intake to fit older engines.

I know of one guy who put an LT1 timing cover and opti on a gen 1 block but it was a HEAVILY modified Donovan aluminum block with welding and all.

Now I believe there is a way to make the LT1 computer run with a late 90s rear mount distributor out of the vans or something. Never paid too much attention because I only play with the LT1s and never had an opti problem.

 

thanks man tryin to decide if i wanna go carb or not

 

Why bother? just get a ZZ383 crankshaft, clearance your block and bore .030 over and you wind up with what 388ci. Plus all your original LT1 stuff will bolt right on and no headaches.

 

check out this article, good reading, great idea!

That is a joke right????
A good set of ported GM heads and a cam swap on a stock shortblock LT1 will make more at the tire through an automatic than that makes at the flywheel.
You would be lucky to get 350rwhp in an M6 with that and that number is doable cam only.
