so what do you do when you go to a older ( second gen.) 350 that only has heads that have the three bolt holes on one end of the heads and you need both heads to have three holes faceing forward for brackets to bolt to. or is the one bolt hole on the head along with the two down on the bottom by the timing cover and the alt. bracket that goes to the exh. stud good enough??? I need to run the 76cc heads due to flat top pistons.

 

depends on what setup you are running. what year car, what accessories, and list anything else of importance. pictures help too

 

Thanks for the reply
!992 rs 305 to 350 swop all standard accessories alt, ac, ps, air pump, using standard cast alu. brakets that came on the orig. 305 the brakets look the same as the ones in my 92 sub. car is not here right now to attatch pix for you

 

hm, that might be tough. i havent worked with the older engine that didnt have the mounts in the heads. what year is the engine? you can get away with using mounts for the engine and only run the alt and ps

 

not shure of the year of the heads they are at the machine shop right now will have them back mon. to cross casting # for year the block is a 92

 

got the heads back yesterday. casting # 3970126 comes to a few different conflicting spec's some say 67-70 327/350 1.94 1.5 some say 68cc. and other say 76 cc. after I finish up the bowel work for the 2.02 / 1.6 valves I will cc. the heads to make sure of what I have before putting them on. As far as the ac. and ps. and alt. brackets anybody have any bright ideas? I have the brackets off the 92 sub. 350 donor motor as well as the brackets off the 91 rs/305

 

Yes, those are 67-70 327/350 heads. Narrowing down the year may help beyond that. There is a date casting on top of the heads as well.

 

you may have to go with an aftermarket acc. mounting system for an engine of that era. i dont think the oem stuff will work
