    Your setup should work fine. I like to see an overall first gear ratio of about 9.5:1 to have good drivability with an aluminum flywheel . Yours is 9.98:1. Be careful with the early M-20 (2.56:1), it had a smaller cluster pin than the later ones (with 2.52:1 first gear). You will be fine if you don't have too many launches with slicks. As to the gear drive - I hate them. They make needless noise and provide no benefit. There is even a possibility that they are harder on the valve train as they don't provide the cushion that a chain does. Mounts - Do the Jim Hand trick. I don't think the Mity Mounts are very good. I think they use cheap mounts and then they add a bolt to them to have the same effect as the Jim Hand mod. Then add an active control on the passenger side. On my GTO I used a shift handle to bolt to the head. It bolts into a bracket I had added to the driver's side of the frame. It is a little loose, but not much. The passenger side is also critical if you have headers that go over the frame.

    Yes, I made it to Tiger Run again this year. I lost in the finals, breaking out by 0.011 seconds. I had a great time!

    Did I answer all of your questions? B/T/W, you should have interrupted me at Madras before. The worst would be that I would ask you to come back later.

    B/T/W, let me know if you get this. I usually screw up the response to the Visitor's messages versus the Private messages.

    Hi!
    I just wantred to get a few opinions from you on my project- I am building a 65 GTO gasser "style" car It will mainly be a street car heres a few particulars front end has a straight axle installed, no inner fenderwells.no radio ,no heater, trunk mounted
    5-gal. moon tank , trunk mounted battery. the engine I have is a 68 WJ 390 horse 428 engine is basically stock except for a RA IV cam and roller rockers I will be going with an old set of three tube headers an old mallory dual point with a pertronix electronic conv. inside.I will be using a s-k warrrior tunnel ram-copy of the early doug nash. for carbs I have two 500 cfm. edelbrock/afbs The rearend is the orig 3:90 safe-t track Which I still need to have gone through Heres a few Questions-----I have a sheifer alum, flywheel and a scattershield, the trans. I have which is fresh is a Muncie m-20 wide ratio with a 2:56 1st. gear I read a few threads which you responded to re: alum flywheels I think I remember you had a formula for horsepwer-weight axle ratio and first gear ratio?? anyway do you think my set-up will work o.k.?? NEXT
    Right now the engine has a cloyes double roller timing chain- I was thinking of installing a gear drive- whats your opinion of these on a street car? whats the big difference between the noisy- quiet versions?? also how about quality I have seen cheap ones for around $60.00 on e-bay(probably CHINA JUNK) and ones some guy in WA. has for $500.00!! What do you recomend for a street car?? NEXT-- How about motor mounts?I thought about solids and tranny mount. but most of the threads on PY guys were against them on a street car-What do you think of the Jim Hand trick of welding a rod on the drivers side mount to limit movement?? What exactly are Mity-mounts alot of guys talk about?? I didnt make it to Tiger Run this year did you?? A few years back I saw you there at the Madras Dragstrip- I wanted to talk to you then but you had a small swarm of people around you and you looked like you had your hands full. Any help or ideas would be GREAT!

    Thanx Alan
    There is a post on PY with a few crappy pics of my rig if you want to check it out.
