Im strongly considering building up a new short block for my Nova in the name of torque and drivability. Ive kind of come to the point in my "hot rod life" where a giant cammed, small inch, 7,500+ rpm motor isnt what i enjoy for a drive around town, to work, to anywhere really. { Eric68 if you read this there will be no need for an "i told you so"} Yeah the thump and boom this motor makes is sweet and it pulls like a bitch through 7500 rpm but its really a pain when i get down to it. Basically im looking at an increase in cubic inches and a decrease in rear gear. This car will only be raced a few times a year and really just for fun, it will see more street time than anything. So heres where the questions start.
My current car/combo looks like this
-350ci sbc, 11:1 compression
-200cc racerites
-team G, 750 mighty demon
-296/302, 258/[email protected], .562/.562 on a 108
-1 7/8" x 3 1/2" super comps out a 3" x-pipe and dynomax ultraflo's
-Richmond 5 speed
-9" rear with 3.89's, when coupled with the 1.24 4th gear makes a "4.82 rear gear"
-Nova weighs 3500 with me in it
I guess my first thought was to get a SHP block from dart, stick a 4" scat crank/rods and srp pistons in it and make 427". Then reuse the stuff i have on the top right now, maybe go to a nice hydraulic roller or possibly keep the cam I have in there now. I dont how know well it would work though. I know the 200 cc heads would be a limiting factor but how limiting would they be? Would this thing take a crap at 5000 rpm with the small cross section on those heads and 427 inches? What would YOU do for a build here? Now remember im not rich,i dont really have a budget per sey but im not going to be buying a set of 2500 dollar heads, although later on down the road that may be a possibility.
So i guess heres my questions.
-1. If I went 427" and reused my 200 cc heads how limited would this thing be? Would it be a stump pulling turd?
-1a. If 427 inches is not going to work well with 200 cc heads, would 400 inches be a much better idea? Would i be giving up much power going with 400 inches?
-2. If I reused my current cam would the cubic inches calm it down a bit or would it still be a "testy punk"
-3. If I reused everything, what kind of power and RPM numbers would i be looking at with 400 inches/427 inches?
-4. Would i be much better off power and drivability wise to drop back on my cam profile. Lets say for sake of arguement i set my compression at 10.5-11:1.
Whats say you??? Let the opinions roll in and feel free to give your ideas that i may not have come up with. Im open to them all.
