Have a 410 for sale. Bought from Benics and had Claxton rebuild. Was told it was a new build minus the block and oil pan. Heads are pro action -12 heads has a hilborn injection. Heads and injection has about 26 races total since new. Motor let go and block needs repair. Very nice smooth running motor and good drivability. Needs repaired asking 5000 obo.
