Looking for a copy of the 390 Cadillac build they did. Looked online, but to no avail. If you don't mind scanning it, the Caddy guys would appreciate it.
This one ended on Ebay about 6 weeks ago. It doesn't say if it sold or not. Contact the seller, or wait awhile. There'll be another issue up soon... http://www.ebay.com/itm/HOT-ROD-DELUXE-MAY-2008-/162400801645
Dude, you're my hero! I'm pretty disappointed in the build though. They put a cam in it, did some porting and it made less HP than stock. Here's the factory GM numbers. Bore and Stroke: 4.000 x 3.875 Piston displacement, Cubic Inches: 390 Compression ratio: 10.25 Maximum Brake Horsepower: 325 @ 4800 Maximum Torque Lbs.Ft. @ RPM: 430 @ 3100
Compression too low, cam too lame, not enough port , restrictive intake I think. We'll see if mine is just as lame when the time comes! Same folks did the work on mine but we went back and forth to the flow bench multiple times.
If I have time/energy. One of the problems with the 390 head is that the intake flow has a flat spot at .3" lift. That was corrected on my heads but was unknown when the article was done (they didn't do any flow testing). The engine may have been over-cammed for the intake flow capability. My heads should now be on par with a a stock high performance SBC head and I'm hoping for more than 4800 RPM! Springs should be good for 6500 but I'm not sure if it will get there.
There is a local dude been trying to sell a big ol Cadillac motor like that for sale . IIRC he has some new parts and motor is all apart. looked clean
