Re: 4.5/4.9 Cadillac V8
Did I mention Honda H23 rods and Toyota R22 pistons ? Boring/honing wet cylinders much easier/cheaper.( lathe and horizontal hone). Mod SBF hedders to fit. A better aluminum head is on the way.

Re: 4.5/4.9 Cadillac V8
Art this page has some info on porting and blocking the heat riser on the center exhaust ports, On a very high performance build I would add steel inserts for the head bolt threads and rocker support threads. Art, are you making heads or using Rover heads with a deck plate and using your roller cam? If the later I think you would have to eliminate the distributor and use crank trigger ignition. Megajolt? Very curious as to what Jack Collins comes up with, on putting one in a MGB.

Re: 4.5/4.9 Cadillac V8
I'm sure there's been something in this thread that speaks to the potential advantage of this over a Rover or Buick 215 build. I'm especially curious about this vs. a stroker Rover 3.5, as I will have some parts left over from my stroker Buick 300 build (crank, heads, 4BBL intake, etc.), and also have a spare Rover 3.5. I saw mentioned the possibility of using Rover heads on this Caddy block--would the 300 heads also work? Mostly curiosity at this point, but who knows.

Re: 4.5/4.9 Cadillac V8
Eric, The advantage is to the Cadillac motor. The aluminum heads are lighter and breathe better than the iron Caddy heads. I think it could be done with a special reground cam because the valve arrangement is different. It would be unique.
