-Some grinding over the finalgear has to be done, and a thin steelplate is screwed in so the oils dont mix engine/gearbox.
Are those Ross pistons made for a SB Chevy engine or are they custom made so that they rise to the top of the SAAB engine block when on the Chevy rods?
-the ross pistons are custom made, with the oilring going through the wristpin hole, its a LOW piston!!
How different are the journals on Chevy rod and what kind of modification needs to be done to make the bearings and journals fit the SAAB crank?
-The crank is regrinded to chevysize, and the chevybearing is used.
I immagine that the light pistons help balance the engine better after the crank is re-ground and that the engine needs to be very carefully blanaced!
its balanced, but in 4cylinder engines with the journals 180degres apart, cyl 1+4 and 2+3 takes out eachother, so its fairly easy. we have a sort of very cheap rallycross class here, and they build 2.5liter engines without balancing, and they "do the job"
We have similar regulations for our "Group 2" class. An engine with 4 or more valves per cylinder is allowed to be up to 2 liters, an engine with 2 valves per cylinder is allowed to be up to 2.4 liters, and pushrod engines and diesel engines are allowed to be up to 3.0 liters. Luke's car is turbocharged so it is in a different class, "Group 5" and I don't think there are any engine size limits.
-ok, so both our saabs would be in group 5 then!
-how is luke finalposition in races, is the saab competitiv in the group??
-it would be a hell of a lot of fun to come over to you in the future and spread some gravel in a good rally, where can i find your rules?? and what is your best rally (webpage please).
