Went.040 over should I expect any probs?

flatyota · 10-30-2009, 07:29 AM

Im throwing it back together tonight. I bought all new .040 over internals from engbldr and a 261 lift cam. Im currently running either a 32/36 or a 36/32 weber carb I am not completely sure it came with the truck none the less I have heard that you need to run a FPR with that carb for reasons of to much fuel. My question is since I have now increased bore and kept the same fuel pressure, volume, spec, ect therefore leaning my engine out pretty dramatically. Should I still need to use the FPR?... and also if anyone else has gone this route or any similar builds... do you like it? what was the outcome, any problems with running hot? I also threw an electric fan on to help a little. Thanks!!!

I haven't heard anyone complain about heat problems at 40 over.

With a DT header, 2.25 exhaust, open intake and that 261C cam, you would see some really nice increase in throttle response. That EB cam works best in a 22R. With .040" over bored you are getting about 3.2 more cubic inches. You will probably need to make sure your mixture is right. What is your elevation and climate?

Google map it and click terrain it will give you a rough idea for elevation
