Lynn , I looked up your block and I read it has the same large cam journals as mine . Was there any problem in finding a cam ? You have a nice list of vehicles , I take it this went in the Typhoon ??

Bowtie Cam - Specs
Yeh, it's in the Ty. Hey, I'm glad U pointed that out. I wasn't aware that the cam J's were bigger. Looking in the shop manual, stock is ~ 1.87".
Conley assembled the engine for me w his own CC roller grind (#CS-3119/3109, HR112 +4). Serial # Y 4234. So, he must have gotten the larger journals.
Not particularly Hi Lift at 0.525" Gross Intake and .510" on the exhaust. The shop manual says the stock Lobe Lift is 0.357/0.390. Multiplying by the 1.5 stock RRatio would give 0.536/0.585, so if this is right, my cam lobe lift is lower than stock ? Kinda surprising !
The stock duration is not listed in the manual, but I hear it's pretty mild, around 200 for both valves ? Mine is 224 Int./220 Exh. @ 0.050", so that appears to be significantly higher than stock. It has a 112 Deg Lobe sep. and is 4 Deg advanced.

Thats close to the spec of the comp cam 422 I was looking at .Its .500" lift and 216/220 duration with a 114 lobe .
Would you see how much he would want for a cam for my motor ?? Same as yours to make it simple .
