Set of 6 Billet 292 7.130 rods. These rods are made to use our 250 forged pistons to give a good zero deck height while allowing minimum deck cleanup.
This setup provides a light weight piston with improved geometry on rod to stroke ratio.
Clearance on tight areas of the engine were taken into consideration when the rods were designed. Engines will need clearance checked in critical areas (ie- oil pump, cam, ect)
7/16 ARP fasteners used.
Far superior to stock rod.
Made to be used on a 2.100 rod journal
Rod BE width is 1.030
Wrist pin size is .927 floating
Billet 4340 rod for the 292. This rod is 7.130 long and allows the use of our 250 piston in a 292.Stock rod is 6.76 long.
Doing this will:
Lower the weight of the piston, the compression height is lowered with a long rod. Allowing the engine to rev quicker.
Strengthen the rod over stock, Rated to 6500 RPM with Piston/ pin/ rings weight of 650 grams. This is a conservative rating.
Weight of rod is the same as stock
7/16 ARP 2000 bolts are used
Floated wrist pins are used.
By using the Long rod in a 292, piston weight is considerably down. A stock piston weighs around 900 grams, the Ross 250 piston weighs around 490 grams. Almost 1/2 the weight.
Got some weights for comparison.
This is comparing the entire assy. Rod, piston, rings, wrist pin and bearings.
Stock rod/ stock piston 1635 grams
Stock rod/replacement piston 1583 grams
Ross piston, billet rod, modern rings 1405 grams.
What will 1/2 lb do to the way a engine revs and react? Per cylinder.
Notice in pictures. These rods clear the oil pump and camshaft on a stock 292. Some clearancing may be encountered on different engines.
Our piston options are either flat top or 18CC dish.
The last 2 pictures show a stock rod with a stock type piston ( it has the round dish). The piston sits .065 below the deck.
The second picture shows the Billet long rod with our 250 dish piston. The piston is .030 below deck. This block is not decked.
