Should I dyno my car?

[pokertramp]

I have no idea how much horsepower my car has. The guy I got it from said it was a 327 Chevy with 375 HP when in fact the motor is a 1975 Chevy 350 4 bolt main. What's the best way to find out how much power I am putting to the wheels?

3 ways you could do it
1) the cheap, not so accurate way..download (it's free) camquets6 from compcams and plug in your info. you will need to know the compression and pick whatever cam is the closest to yours, if it's not from compcams. this will give you an approximate flywheel HP
2)dyno it, if there's one available. quick, simple, and easy but dynos do vary, so the number may not be 100% accurate.
3)dragstrip, get your 1/4mi time, speed and trap RPM's, then you can find a few calculators online that will give you your power.

I know nothing about the motor except it has some power.

The closest drag strip is New England Drag way and thats over an hour away.

The closest Dyno is 5 minutes away, $70 for a 1 hour session and $100 for test and tune.


The block number is #3970010

Front of passenger head is V0630TXD & T7V600223.

Anyone know what this engine is? I keep getting a 1975 Chevy C-20 but I could be wrong.

for only $70 i'd definately get it dynoed.
once my rings seat i'm going to a guy in danbury ct that wants $125.

010 = 350 ci 1969 to 1979

I want to have mine done once the car is running right and put together, and if it were only $70 I would jump on it. My block comes back as I believe a 1977 350, but that means little more than an approximation of the bore and stroke with an engine that old. Most SBC's that get swapped are not stock ( mine is no exception), so casting numbers tell you nothing about the power it makes.
