Turbo Fox project...
 

I've had my block, crank, rods, pistons, etc. for a while now. They've been "aging" in a corner of the shop because of other priorities. I pruned a few "smacktalk" posts out of this thread (including mine), since everything keeps getting delayed. LOL.

Engine will be a 331 and includes the following parts:

4-bolt R302 block
4340 forged crank
H-beam rods
Ross Pistons

Engine management will be a FAST classic sequential box.

Team Z suspension going under it along with tubular K-member and coilovers.
I have full intentions of driving the car on the street, to work, track, etc...

I hear ya' Matt! I know the feeling,my coupe sat under the carport for 3 years with no engine/tranny in it while I built up my 306.Not having the free time to do it all at once can be frustrating!:banghead:

:yup: yep. I had some of the parts before Italian LX even ordered his 418 stuff.

You power-adder guys who've built your motors...what kind of piston clearance did you have in the bore?

I have my sights set on a figure, but I'm curious as to what you guys used. And what type piston and bore size for the given clearances. :nice:

Oddly enough, I was bored, and leafing through an engine building book. This is what the guy says in regards to forced induction piston clearance:

"I prefer to bore the cylinders to within .004" of the finished size, then hone each cylinder to fit a particular piston. In this way I can keep piston clearance to a tolerance of about .0003".
[...]
First using 220 grit stones, about .003" of material is removed to bring the bore to .001" from its final size. Then another .0005" is taken out with with 280 grit stones, and finally 400 grit stones are used to bring the bore to its final diameter. This result in a very accurate bore with a fine finish that requires very little break-in."

give us some SPECS on the motor.:wiggle:

Hmm..."Tolerance on a clearance"...probably along the bore. This must not be confused with a .0003 clearance alone between piston and cyl though! That would lock up in about two seconds.

Well, it's a 331. Compression is a modest 8.5:1 but I don't plan on leaving it naturally aspirated... It'll be Supernaturally Aspirated. :D

Yes, yes. I was going to say something about this guy's horrible writing.

Get that trademarked.

so u going to have a hair dryer grey tapped in there with some long drop cords?:jester:

:shrug: whatever it takes to win as many paper races as possible around here. :D
