carb'd Lt1s
 

What are you using for a harmonic balancer??

I got one for the LT1 but it sticks out so far without the opti I wish I would have checked into one for a sbc.

LT1s don't use a balancer, it's just a hub. Unless I've been lied to these past few years :P

Its a harmonic damper. LT1's balanced internally up front, externally at the rear.

what distributor are you using?

if you're using a crank trigger or sumthing else that deletes the opti use an ATI balancer.....

The fluiddampers are HUGE by comparison and the last thing i want is a 25lb brick on the front of my engine..... My engine builder and I got rid of mine for an ATI the second he weighed my fluiddampr.....

The problem with running a different dampener is that you'd have to use aftermarket accessory brackets. That or space out the pulley I guess, but then you'd have to really know the change in spacing that's occurred.

Im running the stock balancer. I made a custom pointer that bolts to the timing cover. While I was degreeing in the cam, I made marks on the stock balancer at TDC and 35deg BTDC.

I got rid of the OPTI also, and run a standard SBC distributor with 6AL and adjustable timing control hooked up to it.

I set the baseline timing at 35 deg using a standard timing light, then took the car to the track making multiple passes at different timing settings to find out where the car ran the best.

So whats your track times carbed vs stock setup?

Im not going to post up what times the car has run this year untill probably the end of the year. I like to do a little street racing, and there are people that know my screen name here, and check to see if im posting times.

But, anyways all I can say is the car ran much faster than I expected it would after swaping over to a carb. I am very happy with the results.

lol So PM me then -_- I don't race at the track OR the street (other than a friendly light to light).

I'm running a crank trigger and the low profile MSD dist.

Carbs still make more power on the dyno and at the track. Drivability goes to fuel injection but mine isn't much of a street car anymore.:D
