318 build

Good advise so far.Im planning a magnum swap with my 83 cop 318.It has all the usual cop stuff,windage tray,360 heads,4 bbl intake,dismal 7.5/1 compression.

I needed to get hydraulic lifters for an amc,correct length pushrods from mopar,magnum heads.I just picked up an M1 for use with magnums on ebay.Was either buy the intake,build a jig to drill em or pay some one to do it.Figure I came out ahead getting the M1 (for what I paid).

Also have magnum head porting templates.These should? be reusable when Im done with em...

Anyways,your compression will be somewhere around 9 to 9.3 to 1.Perfect for the street.Might be a bit higher depending on how thick your head gasket is and how muck material is removed to deck and square the block.

I wonder if perfect seal rings would work for nitrous?
