A number of folks were interested in Hap's build of these two engines. This is the thread where updates will be posted.

...I dissassembled Ray's 1275 yesterday, looked pretty solid, has a .010/.010 crank that maybe can just tkae a polish, the bearings in the engine looked almost new.

I hope to get the galley plugs out of Drew and Ray's engine today and get them both into a caustic wash, this will be Drew's engine second caustic wash. Hap 4/15/08

Got the galley plugs out of both blocks this morning, Drew's blocks has already been bored, it got a second wash today, and Rays got his galley plugs pulled and his first caustic wash today.

On Ray's motor while everything looks pretty good it does have some DPO to it, someone chisled the crank bolt anbd oil pick up bolt on, I guess they didn't even own a big adjustable wrench , not the end of the world, but nevertheless, interesting approach some folks take with this stuff.

I take off to go to Daytona with a race customer Friday morning, so my plan is to get Ray's block in for boring before I go, in fact this post just reminded me to call my boring guy just now.
 
My carbs in there somewhere, Hap?

What Tony, You have carbs here? :smile: Yeah they are all prepped and ready for assembly, I'll start assembling them today and hopefully get them off to you before I head to SCCA drivers in Daytona with Fred McConnell. Add a couple of butterflies to your tab, your's were junk, so I got two new ones.


Ray's block made it to the boring shop yesterday, and I got his old piston pressed off the rods. They said they may even get the block bored today, we'll see.


Next week, I'll start to move to clean up on these two motors, degreasing everyhting, take all paintable parts, strip the paint, bead blast them, prime them and paint them, once you get past clean up, the job gets to be alot more fun, I don't think I'll ever learn to enjoy the greasy work, maybe that's why I don't work on running cars, none of them are clean enough to suit me :smile:

:iagree:
 
Moving right along! How did my block look (other than the rust)? I've no idea what the history of the engine was, so don't know if it had every been opened up.

Drew your block looks fine.


Tony the carbs are togeher, the manifold and linkagese were drying when I left the shop today so, it will all go together tommorow. I like the heat shield you sent me to use on your set up, it's zink plated the last A-series heat shields I got were black, where did you get it Moss, VB or Engles, looks nice, I'd like to use them again on the HS2 jobs.
 
Zink sheld comes from MOSS.

What do you put on the linkage Hap?

Got it from Moss, Hap...& I was pleased with it also!

I bead blast all the little bits ( I use a metal veggie strainer in blast cabinet to keep a count of all of them)
Then lightly paint them with Duplicolor hi heat cast aluminum, works as good as plating, and you don't have to strip every spare carb set you have down to have plated ones on hand, plus it never blotchy like plating can be sometimes.

I'll post pictures of Tony's carbs later today
 
PANT - PANT - PANT!!!!!
 
OK, next update on Ray and Drew's motors. Both motors are bored now for the AE21253 pistons, both block have been caustic washed, Drew's twice, and Ray will probably get another run thru the spray cabinet as well. First thing I can tell you is letter stamp kit is getting a good workout, or atleast the Rs and Ds are anyway, with two block of the same kind more or less at this point getting the same work done on them back to back, it's important to keep Ray and Drew's stuff separate, so lots of stamping going on :smile: Last week I had drilled out the galley plugs on both engines, and today I tapped both block's galley plug holes for 3/8NPT and fit the NPT plugs. This is not a horribly hard job, but a 1st timer can screw it up if not careful. The 1275 block have a slightly larger bore where the plugs go in (1/2"), then step down a bit, mostly for a step for the factory plugs to seat against. You almost always need two 3/8 NPT taps to do this job, one regular length tap, and one bottom tap, I make my own bottom taps ( you can buy them at specialty place for about 3-4 times as much as a regular tap)by grinding the shorter then puting a chamfer on the bottom, on some applications I have as many as three lengths of taps to achieve the job. Also on a 1275 it will aid you to use a 1/2 drill bit and drill the step a little deeper to make your tapping job a bit easier. The secret of the job is to sneak up on the tapping as to flush the plugs out with the block, 3 of the 4 galley plugs need to be flush for engine plate mounting, one the front one can sit proud, but I flush them all. Sorry for no pictures I left my camera at home in my luggage, just got back form Dayton with a race customer. Next move will be removing the cam bearings, then wire brushing the block, then hot water washing them, and scrubbing all the orfices out with engine brushes, they make little engine brushes to fit all small orfice in a block, you should never take for granted there's not a blockage in any orfices. Then we'll be ready to prime and paint the blocks, another light hot water clean up, and we're ready to bag the block in preparation for assembly, then on to the rest of the assembly as for clean up and prep.

Until next update,
Hap
 
:banana: Happy Dance! :banana:

I really need to get busy on my portion of the work.
 
Man what info. I can just see him leaning over those blocks with tap in hand.
