Comp Ratio??????

[Ram Air TTA]

Just a question,
I just happen to have a good 4.1 that I would like to use in my TTA. Does anyone know what the comp ratio would be with the stock style pistons and TTA heads?? Any help appreciated.

I'm not sure what the stock compression ratio of a TTA is, but with my stock GN heads on a 4.1 the compresson ratio is the same. If you get aftermaket pistons with a different dish volume then you would get a different comp ratio. My guess is that your comp. ratio should be around 8:1.
