PISTONS

[ratpower]

Hi guys,

Quick question. Are stock TTA pistons the same as stock Grand National pistons?

Thanks for any info.

Hi Chris---TTA pistons are different then GN pistons. If you use a GN short block with TTA heads you'll bump the CR from 8.0-1 up to approximately 9.0-9.5-1.

Not the end of the world; I would use them if the price was right--just run less timing in your chip.
