By tradition, with stock type diameter tires, 3.54 to one rear gear will give the Javelin much better acceleration from a dead stop.

IMO, you've learned an expensive lesson; compared to all the money spent to hop up the engine, a gear ratio swap is one the best 'bang for the buck' mods a person can make to their car. ~especially by buying the expensive tall tires.

*you can do the 'rope trick' to install new valve seals...

Well, it could have been a lot worse. I bought the engine rebuilt and mostly assembled for a pretty good price. If I did it myself I would have gone with a different cam for sure.

Other things to consider here:

1.check engine vacuum
2.are you getting a good spark (coil, bad ground - I ran a second ground on a Javelin once, etc)
3.bent push rod(s)
4.Carb not opening all the way
5.balancer slipped (wrong timing marks)
6.compression check
