Well we got the transmission out of the Lark this week, I think we found the cause of it locking up in 1st and reverse… We are going back together with an ATI bell housing and a 1.80 planetary gear set from Sonnax.

Well the new power plant for the camaro is complete…

A 583ci BBC with 12* Rehear Morrison Raptor cylinder heads. Topped off with an EFI conversion and a x275 dry fogger kit capable of flowing 800+ horsepower of the good stuff done by our friends at Induction Solutions which also supplied us with an Accufab 6500 series throttle body capable of flowing 2600+ CFM. looking forward to working with them much more in the future. Tucked under the fuel rails we’ve got some 1600cc injectors from fuel injector connection.
We cannot wait to get this thing between the frame rails!
