I am working on a motor for my 63 Nova and I want to ask some questions on proven combinations. If you have anything to add or suggest I would love to hear from you. For the sake of time I will list what parts I have and you guys can suggest what to use or not to use. I realize this is not an exact science but I'm sure I'm not the first one to do a build similiar to this. My parts are as follows:
-Rebuilt 250 short block, cast pistons, .040 over.
-Lump-port head w/ manley sbc valves, dual springs
-Mallory unilite ignition
-clifford intake, headers and 270 duration cam(all currently installed on my original 194 motor and it runs like crap...no torque.)
-Rhodes lifters
-Stock powerglide and rear w/ 308's
-I have a both a 390 and a 600 Holley I can use.

My question is what do I need to change/fix/etc. to make this a sweet setup? I will take suggestions on any aspect from the cam to the rear-end. I have strongly considered an Offy manifold for more low-end torque, possibly roller rockers, different gears, etc. I am also looking for suggestions on a cam, I have not been overly impressed with any of Cliffords products so cam suggestions are welcome. I am not bashing Clifford, I just don't see why they rave about the torque these motors can produce but sell products that don't emphasize low-end torque. The products they offer seem to be all-out race parts which are very hard to tune for the street. I hope to get some good feedback, it seems like there are some pretty sharp "inliners" in this forum.

What are you going to use the car for, and what are your main goals for this engine/car? We just need to know a little bit more. John

well at this point my 2cents here is. First off this is one of the middle cams clifford offers which is a fair range cam.(listed) (stick only)
if on a stock convertor Not Good. my opion min. of a 1500 stall. step the rear gear to a 3:32-3:55 Go with the Offey better low end to mid ranger tork. Next Question Is what headers do you have the shorties Or full lenght headers?
So main Question is What are your plains for this
motor/car?

Ps other issue hear is are you running a stock head on the 194 at this time? If so this could very will be a issue for that cam. So you do have some issue here. You have some good Parts here But maybe just the comination is not right.

I want to use this car for a cruiser, not a daily driver. I am not so concerned about fixing my current setup, but rather making my 250 combination right. More later!

Thanks
Rian
