im wondering if anyone knows if a lt1 top end will bolt on a old 350 shortblock? is the head bolt pattern the same?

thanks

 

Not without serious machine work to the heads.....

 

Absolutely no rhyme or reason to put LT1 heads on a Gen I SBC. It's never been done, for several reasons.

Short answer, no.

 

thanks ive never compared the two block and gota rebuild my lt1 soon so thought id try and get a answer on that.

 

Actually, the LT1 heads and intake are popular for the 3rd Gen guys. Its a matter of plugging up a couple coolant passages and drilling a couple new ones. Cheaper and lighter than a set of Vortec heads.

In addition to the head coolant passages, the entire front of the Gen 1 SBC and the LT1 blocks are totally different, due to the water pump provisions and the Optispark distributor drive.

Also requires a remote thermostat.

 

x2.

 

thanks frank that is what i was wondering.
it was just a thought and wanted a good answer. not just there is no point or why would you do that? thanks for all responses though helped my reasoning allot.

 

It's really only economical to swap if you can do the machine work yourself. Once you pay for someone else to do the work to the heads you'll be into the conversion for what a good aftermarket heads will cost.
