Backyard freshing up a race motor on the cheap

Backyard freshing up a race motor on the cheap - 03/11/09 02:01 AM



So i dug my old 451 out and tore it down to see whats up.

Its going to need one piston (ross dome) due to the smallest of pinched ring land, rings and a hone job.

Question, do i need to haul it down to the machine shop for a torque plate hone or can i achieve good ring seal with an at home hone job? the motor had about 100 or less passes about 1/2 with heavy nitrous so the rings just gave out.

If i fire it up and it huffs and puffs like a cho-cho train I'll be pissed, but i don't have any money to waste ether.

all opinions accepted, thanks.

for the cost of a hone job it's not worth the risk imo. also depends on what you intend to do with it? more juice?

I should add it was originally filled, and bored then honed with a plate and was one of the best sealed up motors evar!

Hi Tony, it will see as much nitros as can flow through a 906 head and that aint much.

I'm quite sure you right, the plan was to have the guys around the corner from me hone it. As far as i know their the only guys in town w/ a plate and they did a super job for me last time!

Then the bottle brush thread got me thinking....

If you want it to last, why be cheap? Kind of like being married, then get a divorce for some bullshot.

I'm working on it, money is non existent... but i don't need to much to have it create an even larger carbon footprint than i already have going.

It wont be fast tho. Mid 9's i suppose
