Actually Dave is really prompt and his delivery and promise times are spot on. I've never had a long wait with him

Re: Dyno numbers 305
 

On time for sure. Not usually "next week". LOL

Re: Dyno numbers 305
 

For the ones that have kept up with the 305 build I BLOWED it up already. It was 2 tenths slow rnd 1 at the gators. I guess the valve face jammed into the head was reason why.
I put a order n at cp today for 2 more pistons. I need a spare just in case. Few weeks I be back together hopefully.

Re: Dyno numbers 305
 

Just too tight PTV clearance? Or did the valve drop?

good luck!

MR. P billy, what thickness head gasket Did you use ? M.J.

Re: Dyno numbers 305
 

Tough break...
hope you find out why and fix it fast!!
Good Luck :)

Re: Dyno numbers 305
 

My first go around with cp wasn't the best. I had to purchase a couple more pistons. This time I called Darin at Patterson and tht is one good dude. It's been 8 days and pistons are being shipped.

Re: Dyno numbers 305
 

Darin is top notch. I have purchased all of my pistons and rings through him at Patterson. Great guy to deal with.

Re: Dyno numbers 305
 

Phil,
Did you find piston/valve clearance problem? In picture you sent me it looked like you had some intake and some ex but not all of either hitting with it being somewhat random I would look at valves see if all same thickness and setting same depth,if they are the same probaly getting valve float with it being kind of random springs may not be set up evenly and have some with less pressure, all that is ok double check actual clearance piston to valve clearance.
I know valve broke had head popped off of stem that alot of times is sign of valve float,hitting piston did'nt help head stay on valve,but float will pop off heads of valves stretch and burr keeper grooves,can leave X or * asterick pattern on tip off valve where roller on rocker is beating on it,and timing chain stretched ,valve guides wollared out prematurely are all symptons of valve float.

Mike all the intake valves was hitting. I haven't taken it apart yet. Well short block anyway. I did find a couple sets of 416 cores so I got them parts. At least it isn't to bad I guess. Something's shouldn't be rushed! It isn't the first or last I am sure.
