What I would like to do, is bolt the TBI intake on the 85ish Motor. I hear the TBI intake mount bolt angles are different going into the head. Can this be done with minor modifications, or is there a whole lot more to it?
You will need to elongate the bolt holes on the TBI intake manifold....
na they make adapters for the bolt holes. They can either be used to put an older intake on a newer motor or vice versa.
When you buy the China made intakes that Summit sells, and on eBay they come with the adapters. The holes in the center are larger for the adapters to fit in. Even if you elongate the holes the angle of the bolts is different and they dont sit on the intake right. It does work though and has been done plenty of times with success.
If you read the description for this intake they mention the adapters, and you can see how big the holes are for them to fit in. It is just a bushing that fits in the hole and the top of it has a seat that corrects the angle. http://cgi.ebay.com/ebaymotors/PROFE...spagenameZWD1V
thats what i was referring to. I acutally have some of them laying around somewhere. If you want to go old to new pop them in, if you are going the other way, flip them over and use them.
for what its worth, i have a set of freshly rebuilt centerbolt heads. completley gone through with new seals, and everything else they needed. My buddies dad is the head man at the machine shop so he did me right on them. ill let them go for 200 plus shipping. was gonna use them on a new shortblock but went ahead and bought a crate motor.
