I got an 89 350 forumla, I think this is the L98 motor. Well, I just have the heads and all for the motor. What is the stock displacemnt (cc) of the heads? Also what are the valve size? I can't find them anywhere.

Also, can the LT1 intake be modified to fit the old SBC heads?

thanks guys!

 

got a casting number on the heads?

 

not with me. They are 350 tpi from an 89 forumla. all those should be the same, right? oh, they are iron, not alu

 

I am not sure of the deplacement...but the valve sizes are 1.94"/1.50".

 

thanks. Anyone else know the displacement? Are these worth rebuilding? Thanks!

 

Would have to get a casting number to know if they are worthy heads or not.

 

Yea, get those casting numbers to be sure, but for the L98s, the chambers should be 64cc. They can be decent heads with a little port work.... better than alot of other stock heads out there.

 

The Lt1 intake can be modified to fit. Expect a lot of work

 

the # for stock 350 TPI iron heads will be 14101083

 

64cc, cool, thanks, that's what I needed to know. Still not shure if I'm going to keep TPI or go carb.
