200cc too big for mild 350? pics
Hey I scored big time. My uncle has Carpal Tunnel Syndrome and was forced to retire from GE. He has given up on his 70 Nova project so he gave me his engine..for free yes!! for free!!
I helped him put it together over the years but it sits on the stand and never turned over. Please don't kill me with the "why did he?" questions but I believe my uncle was triyng to copy or make better one of his work buddies Corvette engine so he may have been ill advised.
Here is what it is:
-2 bolt SBC 350 short block with all new stuff like Pistons, crank, bearings etc
-Summit 1103 cam: 288 int./298 exh. 0.444 int./0.466 exh. 112 Lobe Sep , he added 1.6 roller rockers so now it is at .473 and .496
-Polished Vortec dual pane intake with a nice early 80's Corvette Q-jet, double roller cam gear and Ceramic headers
-Nova has a 200-R4 tranny w/shift kit, stock stall with 3.73 Posi rear
-Heads: Skip White's NKB 272-200 that are 2.02/1.60 valves .550 max lift and 200cc intake runners
So here is the question Are these heads too big?
When he bought the heads I told him they might be too much intake volume and that he might need need a bigger cam. He said his buddy told him he'll have more power as he moves up on RPMs with the smaller cam and he should be fine. These GE Tool & Dye makers have a reason for everything so you never know. I think this guy set him up wrong so when they race his corvette leaves him in the dust
So do I run it or sell the heads?
My uncle's Nova has a cammed 305 I put in for him and drives fine so he is giving up on the 350.
I'm dropping this engine in my Convertible so I would need to invest in a new tranny and rear end. Pics have the wrong date(older digi camera)
