What Tim said...I have a sink in the garage...still manage to bring in crud now and then, but my lady has been putting up with me long enough that she is used to by it now. Yea I have a sink in the garage also but lately I haven't been able to resupply my stash of Boraxo so I have been going into the house and using the kitchen sink to wash up, ticks off my bride no end. Need to resupply my hand soap to keep peace in the family, hell after 46 years you would think she would get it? <!-- / message --><!-- sig -->
Congrats Tom.... Spent the day hackin n hewin the valve guides to match the ports now on to the valve job.......
You are a glutton - I always had problems with valve stem wear with the splits. You're not running mushroom stems are yah?
The difference is that the factory split guides used 5/16 stems - and the typical SBC 1.6 Pro-Flow valve uses a 11/32 stem. I used to run the early 59AB split guides due to having a smaller stem in the valve pocket area (and I reworked stock valves on a lathe). The single-piece 49-53 guides were always 11/32. Once the SBC 1.6 Pro-Flow valves became cheap and available, they already had a smaller stem in the pocket, nicely flowing shapes, etc.. There was really no reason to ever go back to the 5/16 split guides -- they are hard on valves, don't seal that well, are harder on the valve seats (move around more) and don't transfer heat out of the valve as well (especially on the exhaust side). Also, I prefer to have the SOLID guides on the exhaust side (no groove for the oil seal) - as they transfer heat from the valve better than the intake ones that have the groove. It is not a bad thing to get the heat out of the valve and transfer as much as possible to the block . . . cooling the valve in the process. Hope this babble makes sense! B&S
Yea Dale they are old style on the intakes becaust they are what came with the block and for now what I am going with to start with. And besides its not a street engine. New style on the exhausts.........
Carl, I have a whole bunch of decent used one piece guides. PM me if you want them I'd send them to you happily if you do. Dale, what you posted here makes pefect sense.
Thanks Tim but I have new two piece guides for the intakes which I will ream to fit the exist valves and the exhausts are in good shape so I'm good to go with what I have now, of course if you have a Potvin 425 laying around that might be another story, heh, heh, heh.............
Looking good Carl! Hope you make it to Eagle Field! Also looks you are ahead of me!? I had to do some more mods to the crank and block before final assembly. Br Kjell ................................. Taildragger&Fenderless
I don't know if I am ahead or behind, seems like the faster I go the behinder I get. Crank was supposed to be finished on friday at the balancers, but nope not even close so maybe tomorrow....oh well still have some more work to do on cleaning up the block boring out the two holes to final dia that I sleeved and other wonderful things to do. Anyway we took the weekend off to go to Monterey and get the cobwebs out so now maybe I can get back with the program...................
Looking good Carl. Contact Pete1- I know he has a master for the 425 Eliminator, so he may just have one 'laying' around!
Like your bar. I have a 777S like that and use it ALL the time. Mine has a red paint job and I have a home made boring table but for 400$ it is the shits, like this thread!
Got the two sleeves punched out and ready for pistons, got the intake gasket enlarged, port matched the 4x2 and am tired of hand grinding, now on to the valves......... And for a little eye candy..........
I had Pete1 grind me a 425 for Bonneville this year... he will just need a good core. Roseville Carl - where can i get that boring machine?! badass... and would save a handful of bucks too!
Yea Tim, I know but it looks like I won't have the new bullet done on time, haven't got the crank back yet and it may be early next week before I get it......but I did get some work done on the valves, got them ground and its off to the seats next........
Well got the crank back, balanced and new keyway for blower drive, finally now its off to bigger and better things, "and the pistons were hung on thier rods with care in hopes that Carl would soon be there" .........
Hey Carl - just came in from the shop and saw your post - awesome, can't wait to see it together and burning the hides!
Yea I know Pete, I'm still working on it, and the 425 Potvin grind, gotta take it a little easy for a while on the ol pocketbook ifn you know what I mean, enjoyed yakkin at ya the other day and thanks for the info I will definatly get back to you!
Fun talking with you at Eagle...Keep up the good work, the car is looking great! Looking forward to hearing the new engine.
