finaly took my 454 apart and man did I blow this thing up.big hole in the block near the timing cover,broke the crank and 2 rods and cracked 2 pistons.heads are fine(I think) and the cam&lifters.my crank and rods where stock (cast) the heads are 820 gm 1971 oval 113CC with some porting.the cam is a roller but can't tell what kind form the #z9086 3052 3053 hr12 K295 do any of these # mean anything to you guy's?

 

Dunno about the rest of the stuff, or if what brand cam.

The 3052 and 3053 are 230/240 durations on comps cam, doesnt mean this is. HR12 most likely is hydraulic roller on 112 lobe???/

 

I missed it, but how did you blow it up. what let go first?

 

the engine

 

called comp and I talked to tech,it is thier hyd. roller but they told me Z9086 is a FE ford.he said are u sure you don't have a big block ford.lol

 

Well, are you lol

I found that number in there to when I was looking, but I was not about to say you had a ford cam in there lol

 

I checked the cam again this morning and yes it say's Z9086.someone must have marked the cam wrong.comp marked this cam by hand so who knows.
