ATR H22a7 Rods and Pistons 11.0:1 CR

Post by **NafemanNathan** » Wed Jul 24, 2013 9:44 am

Change of plans, again

Means my ATR rods and pistons are up for sale.

This set up will see you to 11.0:1 CR, and these are what Rich at PAW uses in a lot of his builds (including his own) to see 270bhp+ builds with oddles of torque.

PDE Rods with PDE Pistons (B's)

PDE Pistons (A's)

Currently the rods have the B's fitted, but whoever buys the rods can request whether they have the A's or B's (or both).

Rods with either Piston sets £100 ONO
Either Pistons Only £50 ONO (Will only sell after the rods have sold or if there's no interest in the rods.)
Rods with both set of Pistons £125 OVNO

All options plus postage or I can bring them to the National Meet.

As Nafe says its the pistons that are A's or B's and are slightly different sizes.

If you peek at the back of the block on the top near the water pump, your block will have A,A,A,A or B,B,B,B or some combination of. You need to match the piston sizes to your block.

Yar it is on the short block. There is a little shelf where the short block connects to the head, the letters point upwards. More than likely they will be covered with oily goo.

Hey @Drax. Didn't want to crash EG_H22's thread, but just thought I'd ask if you want me to bring the rods and pistons to the National Meet? Even if you haven't found out whether you want the A or B pistons by then, it'll save on postage and be a cheaper option to simply send the remaining pistons back to me if you decide not to hang on to them.

Let me know bud
