my 403 rebuild
So I decided to rebuild my 403. I bought a kit new
cam and timing chain with valve springs. I also
baought a 1406 edelbrock carb. Long tube headers
with a turbo 350 trany not posi yet but soon to be. I
ran it today for the second time. It seems ok just
not much power. So what did I do wrong it wont
burn out either.... Spent so much. Just woundering
what can I check to see why I dont have much
power. Any tips?
double check the cam/crank positions~
How do I check that? I don't have a sencer for that on my 403
there are two dots...make them point at one another~
oops...straight off the press...the dots will point even if eatin' a plate of spam~ was actually amazed that I could find an olds 403 engine picture so easily~ she's real fine my 403...she's real fine my 403 my four oh three~
that carb might be a little fussy...the cam if oversized will lead to TERRIBLE idling~ so there is that...so glad that you selected a standard cam...heavy duty clutches will KILL your foot...a no no, I've found~ Standard oil pumps are preferred...heavy duty will produce so much output they will need to be regulated...will cause leaks and be quite a nuisance...go with standard duty everything...anything else will mean trouble~! ...in my humble opinion~
this one even has a groovy imaginary line goin thru it~
Yea I remember I had that lined up rite. Ill do. Compresion check tomaro to see were im at. If I were to do somthing to the bottom end what would you recommend?
Ok ill look into that. Well I just bought a rear end off a 396 chevy camaro so ill have to ask the guy. I started to fix my car at age 17 im 20 now and still learing more about all of this so im new to messing around with horse power.

Precisely dialing in the cam is a key step to getting the most out of your engine. This video is for a SBC but the principal applies to your engine --- http://www.ask.com/youtube? q=how+to+dial+in+a+cam+in+a+small+block+chevy&v=XKtsHqHDX 2A&qsrc=472
I would buy an Edlebrock intake manifold to match the carb.
go juice!~
If the final gear ratio is really high (which I am sure it is), acceleration off the line will be weak.
Something like 3.73 would be good.
So I checked my compresion all cylinders checked out at 120. Im woundering if it could be my trany or the rear end. Its fast but nust wont burn out
How can I change the gear ratio?
