I have a 86 TPI intake.How hard would it be to make it fit a 87-88 350 TPI motor.And is any one selling one.

 

Its not too bad, you can just elongate the holes. One area by a bolt will get a little on the thin side but it will be ok if you are careful. I cant remember which hole it is offhand. If you have the means, machining a flat area for the bolt head and cutting that down a little will help, because the bolts will stick up some and interfere with the runners a little bit when you are putting them on.
