Reply to "Monster 2786 Type 4 build"

My engine builder is called this morning to let me know that the camshaft is broken and the cam gear is a little beat up but everything else is not harmed. He is going to split the case and replace the cam and lifters and check everything out. He ordered a new set of factory flywheel to crank bolts to replace the ones that came loose. I am going with the hotter cam to better match the 48/38 stage 2 ported heads. I am going with the Webcam 86b/86c dual duration cam which has the following specs.

Web Cam Type 4 Camshaft, 86B/86C Grind, 00-662 is designed for Type 4 engines, and it's specs are (In/Ex) .500/.507" Valve Lift with stock 1.3:1 Rockers, 300/310 degrees of advertised duration, and 260/272 degrees of duration at .050". This is an outstanding Type 4 camshaft, longer exhaust duration to aid with the pitiful Type 4 exhaust port! This has a fantastic midrange and top end, and is one of Web Cams best Type 4 grinds for big engines, with a powerband from 3500 to 7000 RPMs, the more headwork and carburetion the better the top end will be.

I think this cam will be perfect and I can't wait to see how it runs. The builder is going to sort out the suspected head to cylinder leakage. The engine was a brute  with the smaller cam and heads leaking, I really can't imagine what it will run like now.     

I have decided to hold off on buying the Red Puma. Too many things going on now to add that into the mix.
