Re: traded a pellet rifle for a 350 today
Any ridge in the top of the cylinder? If not, a simple dingle hone and some new rings will be fine.
Was there any info stamped on the nose of the cam? |

Re: traded a pellet rifle for a 350 today
Well, just went out to check again, and there is a slight ridge. Figured as soon as I was able to see the cam nose, the numbers would be right there. Actually the nose looks rough (made like that I reckon) has a CC (one C stagerd over the top of the other C) and a 2 * 8 H (real rough where the middle number should be) Other numbers on the rear but can't make out all. Like 12 210 and 6698 across the bottom.

Re: traded a pellet rifle for a 350 today
Hmm. Didn't think about the ridge the other day. Better to bore it .040 if there is any ridge at all? (think I know the answer)

Or...if you screw it back together and it squeezes decent compression, leave it be. As for the cam...."CC"? Crane Cams? 2*8?....268, 288..those were grinds for chevys. Under the Crane Blazer series they had the 288H. Crane H268 206*/206* @.050 268/268* adv. 112LSA, .448/.448 lift rpm range 1500-4000 Crane Blazer H288 226*/234*@.050 288/296adv 114LSA .458/.473 (1.5 rocker) (this is technically a Pontiac grind, still looking for chevy numbers.) Most info on an H288 Crane cam points to a solid lifter cam. I'd be willing to bet you have a 268. |

Re: traded a pellet rifle for a 350 today
Way clean on the inside with blue head gasket material---not original---must have been a refresh at some time.
The RWS pellet guns are great--got any more--I have a 350---010. in the barn just hankering to trade for a RWS??? hehehehe |

Re: traded a pellet rifle for a 350 today
Was the only one I had Huck. Deff. was rebuilt, and bored .030 over. Was just surprized at how clean it was inside, considering it was FILTHY on the outside.
