Any update on the Quicktime bellhousing starter nose support issue?

Just going to run the nose unsupported and see what happens.

The Comp rocker arms measure about 1.47 effective ratio on these heads which isn't bad. I like the oiling setup on the Comps with a hole that shoots oil right at the roller tip.

I have ran a Lakewood scatter shield with JW 'wheel' and Bert trans in dirt cars with the Mopar mini starter and no nose support with very few problems. The engine was 408" w/12:1 CR. To mount/align the starter with the 'wheel', I had to make a shim plate to put between the starter and mount surface of the bell housing. On an occasion or two, we would have to re-position and re-tighten the starter as it would move a little and not engage smoothly after several hundred laps. Not a huge problem, but not 100% fail safe.

Why no chain tensioner? The chains on SB are so long they seem to get sloppy real easy. MP part #P5007709.

The last chain tensioner didn't last very long so this time we'll run it without one.

I got a set of RAS rocker arms to try on this motor. Very nice parts, just like their big block rocker arms. Heavy duty hold downs, bronze bushings, stainless investment cast parts, etc.

Also tried a set of PRW rocker arms. These rocker arms come fully polished which is kind of unique. They are similiar to the Comps but have a bushing and a little different oiling setup. The PRW rocker arms come complete with hold down hardware while the Comp setup is just the rocker arms and the shafts. I went with the hold down kit from Hughes to install the Comps which adds another $85 to the system.

autoxcuda,
Roller timing chain really cut into the tensioner in no time. Yes, that engine was run hard and HOT but oil pressure was always present. Maybe its meant only for factory link style chains??

Here is a picture of the tensioner after just a few hours of operation. This part was failing quickly. The chain was eating grooves into the plastic pad and dumping plastic chips into the motor. In a little while it would've been eating into the spring.

Picture of the RAS rocker arms. These are 1.60 ratio with bronze bushings and oiling to the roller tip. Very nice parts.

I read this thread back in the beginning, didn't realize there was this much info here now.

I've seen similar results with the tensioners others have brought to me...I will never use one EVER!!

This build is perfect for my D100! Do those new Comp roller lifters require bronze bushings? What bearing clearances are you running? Any block oiling modifications? Decided on an oil pump yet? Sorry for all the questions, LOL

On the engine

Hi Andy did you use the 12 an and what are the allen screws on sides for
thanks

Yes, I'll use #12 AN on the dyno but I think that car is plumbed for #10.

I don't know what the set screws are for, maybe a place to hang a oil pressure gauge or maybe a handy place to plumb in the valve spring oilers or something.
