Re: Steel Main cap material

I applaud your efforts. Not many amateurs would attempt this on their own. The little BMC engines have a spot in my heart. My older brother had a Morris Minor circa 1960 and he left me tools and instructions on how to dissemble the engine in preparation for a sorely needed valve regrind. At age 11 i...

Re: Question about Little M main cap material.

Will a Rockwell hardness test tell me much about the composition of the iron main caps on my SBM project? Aftermarket four bolt caps are available but many in the Mopar world dont think they are needed at my target 650hp power level. Most argue good 1/2" main studs are all that are needed. If I am g...

Re: Connecting rod weight change...

Update....got the rods back last week.

The shop has the Tobin-Arp rod boring machine. Worked slick. Installed new rod bolts and all is good.

Thanks to all...

Re: Filling aluminium head with brazing rods?

How about using a MIG gun with a spool gun?

I've seen blocks repaired with these units and have been OK for many seasons of use.

Re: Too late for a half fill?

Well my knee surgery has been postponed due to the Kung Flu.... I think I will fill one of my spare SBM blocks that have not been machined then run a hone thru the bores to see if anything has moved. The 885 is hard to find there is a dealer in CA that will ship one bag...$40.00 plus shipping. I thi...

Re: Too late for a half fill?

Is a filler that doesn't expand when cured really going to be effective? It might make you feel better knowing it's in there, but is it really doing anything? There needs to be preload or else once loads are applied, things will still move until they meet some resistance. Preload is good. Preload i...

Re: Too late for a half fill?

Why not take it back to the machine shop? :?: They can do the fill with an appropriate product and make the cylinders round again, if need be. Right now its a logistics thing... What about using Embeco 885? Users here seem to have good reports of no distortion after the machine work is done. That 8...

Re: Engine Oil

I'm going back to CenPeCo SAE 30 in my new build. I'd prefer synthetic but not with alky. CenPeCo ran great in my dirt modifieds and my dealer delivers right to my door at good prices. Using their gear oil, too. Walter is right... Oil is a personal preference. I know guys running WalMart oil without...

Too late for a half fill?

Got my SBM bare block back from the machine shop....bored, one sleeve and skimmed the decks.

I ordered a half fill to be done but it wasnt.

How bad will the cylinder distort if I fill it after the final.machining is done?

Re: Epoxy For Blocks

Here is what i used on a 409 block with cracked water jackets. I welded it with muggy weld and put AB epoxy over it. Let it set up and pressure tested the block on both sides for over 30 minutes at 40psi. No leaks, so I am happy with the repair. WTH is Muggy? A brand of cast iron welding rods.

Re: Jones Cams

The first night my son ran his b-mod the previous owner, who helped us with the set-up, was amazed at how fast my son's car was off the corner and down the straight.

Pulled like a freight train.

Re: Brake in oil

He's using Driven SAE 30 or 40 or CenPeCo... both high quality oils. I like to use a high filtration filter on break-in, too. Then swap to a WIX 51515R. Next season I am going to dyno my engine then change the filter and go racing. Put a couple nights on thevcar then change the oil. From then on I m...
