After having quite a few Pontiac Trans Ams in my younger years and both my girls out of college and onto their careers I decided I wanted to get another Pontiac Trans Am. My very first one when I was 19 years old was a 1971 455 HO 4-speed car, so I knew of a friend that had a 1970 Trans Am but had no intentions of selling it…Well after a few persistent phone calls he decided to let me take possession. I decided I wanted to personalize it and since the original engine was long gone due to a piece of the connecting rod lying on the transmission crossmember, as I was told, I decided to have a 1970 POntiac 455 HO block 4-bolt main built into a 465 C.I. I added Eagle Connecting rods with D.S.S. dished pistons to give a 10.6 compression ration with the Edelbrock 72 cc cylinder heads, added a Crane hydraulic roller camshaft and top it with an Edelbrock Performer RPM intake and a PRO Systems 750 Carburetor , It ended up being 490 H.P and 551 Lb. Ft. of torque. I backed up the engine with a Centerforce clutch setup and an Auto gear M22Z 4-speed Transmission and a 3.55 12 bolt posi rear axle. I'm running M/T street radial tires on Weld Draglite rims.. It's a nice easy to drive on pump gas combination with plenty of torque!!
