Granted, this is more race car than street car with a spool, 8" converter, etc. It also has a 2.45 low gear 904. Not knowing you timeslip deatails, the first thing that I notice is a low 1st gear coupled with a pretty tight conveter. It needs "flash" off the starting line to get it moving. Tell us more...

That is drastically hurting the ET #2 I'm not so sure I'd be running 1.6 rockers on that. I am assuming these are untouched heads? #3 Your back half MPH ( from 1/8th to 1/4 ) is a little weak. Its not pulling enough MPH there. I'd concentrate on that 60' first. It will really improve that ET. How many passes have you made in it? Is it bogging, spinning, coughing etc on the launch? What jets are in the carb? RIP Monte Smith Your work is a reflection of yourself, autograph it with quality.

Brian's Duster with my 3500 verter went 1.43ish 60's. There is something wrong, the MPH is very low. Should be in the mid 90's at 1/8th post if this is a 3300 pound car. If this is in a 4500 pound tank, then take that into account.

Also, as someone else mentioned, what jets are in the carb and does it have power valves in it? If these things are in check I would have to ask if you are sure the converter is good? Everything else being in check it could be a bad converter to knock performance down that badly.

Can you push the car on a flat/level surface without much effort? What type/size tires are on car? A lot of info is missing! Last edited by SeanD; 08/28/10 10:04 AM.

The engine is in a 67 Barracuda Yes there was alot of slippage, non glue at the track, but even that, I should have a better top speed.. I checked the carb before going there There is more effort to push a car with a spool for sure... I start thinking may be the problem is in the trans itself..... Dan

Your 60' is terrible but the mile per hour is way off also. There is something wrong whether it be timing, carburation, fuel delivery, engine or drive-train. Pick a spot and sort it out. Getting old just means you were smarter than some and luckier than others.
