When it ran 10's (last year)it had a 408 eddy motor with ross slugs in it,600 lift roller cam,dougs headers.I have since put in a stock stroke 360 with the edelbrock heads,904 trans,410 gear,35 sline moser axels,spool.I didn;t think I would have funds to race this year so I put a little more streetable combo in it and will save the big stuff for next year.
