Thanks for posting. Anyone know the appropriate method of modifying the blast tube?

Also if you're running straight 100 weight oil in 40F+ ambient, your oil temp redline is increased from 225F to 240F. Surprised no one has mentioned that.

What didn't I say?....

Overheard this weekend (name withheld to protect the innocent) was a modification of a blast tube with an old (PMA- passes my approval) lawn chair. Same size tubing and already bent at the correct angle.

I love that. I was looking over a friend of mines Championship winning hot rod (British oval dirt racing) and asked him what steel he had used for the suspension arms (He is obsessive about unsprung weight). I said "is it 4130 ?" He replied "no, it is table steel". I said "whats that?", he said he had cut it off his wife's garden table.
