4.56 should really help that lil 331 out and should work ok on the street with the tall .67 overdrive. Makes the final drive ratio 3.05 which will work ok on the highway especially with the power range of that motor/cam. I don't know much about that cam but I bet a 3,000 stall lock up converter would work well and is still on the cheap end of the scale. A lot of people think excessive rpm is cool but I tell you a lot more torque and the same HP only in a much lower more useable rpm range would make this thing a lot sweater and provide less maintenece & better reliablility. Just an fyi and something to thing about the next time its apart as good fresh new aftermarket 400 cranks/rotating assemblies are available cheap.
307 to 327 swap.

okay since I dont think anybody has said it, that 327 should kick *ss, they are good motors, epecially with high compression, it'll have torque all day. Now the exhaust, just put some down pipes on the manifolds, tie up the exhaust, go to exhaust shop. Tell them you want use your exsisting piping but the manifold locations are different or whatever. They should be a able to cheaply fix your problem, as your not asking them to put a whole exhaust system on.
i went there the other day to have my tail pipes put on and he wanted 150.00 :shock: and he also said because it is an 86 he will not set it up without a cat.SScamino said:
just gut the cat yourself, use yours cut it off, gut it, tell him to use it. haha. Thats what mine is.
Torque all day? Thats why you sure it up with low gears & a higher stall converter to get it spinning where it does makes some torque. Not a problem on a light drag car etc but needed if you want to "make the most" of small cube street strip set up with a full weight street car. Good lil engine none the less and you are right compression helps a bunch & is needed to match with a healthy cam. Then again I was spoiled with big block low end torque where low gears and a big stall are not needed on a street machine to make it quick and l like to set a car up so that I don't leave anything on the table. On the converter you can legally install a "temporary test pipe" it just has to be removable. Naturally if you did go through a dot roadside test you had better not still have it on if you ever went through a second dot roadside test.
I second the 327 compliment 8)
A 327 is an excellent engine. I would rather have one than my 350. The $150 isn't bad to have a Y-pipe made. You will pay atleast a $100 for a Y-pipe from SummitRacing. I also agree again with the comment about your "cat". Just have him use your existing "cat" and then cut it out afterwards.
BTW, you cannot compare a 307 Olds and a 327 Chevy and say "20 cubic inch more" 307's are no better than a 305 Chevy

the 150 was to put my tailpipes on my car, not a y-pipe thats way too much for 2 welds :shock:RITTER said:
Chevy left the 327 for the 350 because it was better for the street ie more torque and slightly better power range longevity etc. Its fits in the older we get the better we were catagory. Although in a light drag road race car etc where you are going to gear accordingly it can stand the constant high rpm better.
