 New cam is still a flat tappet and number are 106 lobe seperation, installed 103
With 1.5 rockers .637 lift intake .643 exhaust
1.6 rockers( which I've also been considering) . 680 intake .686 exhaust
Duration@ 50 282 degrees intake 287 exhaust
Intake open 38 BTC closes 64ABC

I have been running 33x12-15 M and H RaceMasters on a 10" wheel for about the last 4 yrs and have been very satisfied. They don't show up on their website, but they are a 15" version of their 16" nostalgia topfuel tire. Their part # is MHR-69.

Spud Miller's Cave / How much spark advance with alcohol?

« on: June 05, 2014, 03:52:08 AM »

Hey Guy's,  Just started playing with the timing after switching to alcohol, add was wondering where you are at. C hecked the timing after switching to alcohol end of last yr , and was at 28  degrees. 8)Bumped it up to 36 this last weekend and did' t see any marked change.  Plugs looked good, 2 treads and witness mark on the corner of the strap. Any thoughts? My combo is a 415 sb mopar with Indy alum.  heads, 12.8:1 CR with a . 590 flat tappet cam and an enderle dual toilet on a tunnel ram.

Mr Fitz,  I had the same problem with my car when I first started running it. I tried lots of things, but the bigest thing I found that helped my car was lowering the wheelie bar. I run mine set at about 2 1/2" . You can also try differant tire pressures from side to side after you know your tire rollout. I run mine at the same pressures now, but running the right tire a 1/2 pound lower than the left also helped.

Rodger:
 I will assume this is a compression ratio around 12 to 1.
If the bearings clearances are typical bracket race: .0025-.003" we use 10-40 Brad Penn racing oil.
Everybody will have a different view on this but we have used that oil with ZERO problems.
Spark plugs are also a topic of preference. We have been using NGK plugs for the few years.
They are very easy to read and not over priced.
I would start with a R5671A-7. The short number is: 4091.
Tighten up the gap to .016-.018" for the mag.

Thats my 2 cents:
Matt

X2.  I' ve been running Brad Penn 20-50 for 3 yrs...no problems. Also running the same ngk R5671-7' s gapped @ .025 with MSD AL-6.

Thinking about changing to treaded fronts for more of an old school look. Any pros or cons over a new style slick?
