300 adversized duration in a 283 will be allot harder to deal with on the street than 300 in a 383 kinda thing, just thinking out loud

the tach appears to be over reading imo.
post a driving vid when you get one.Its always appreciated and a good motivator for others to see and hear

Thought I would bump this thread up, it now has a Holley 750 double pumper on it, it's quicker for sure.
Also, made a video of the truck. (it hesitates to start for a second, because i had the choke in the wrong position)

Yeah, the truck runs great, though like was suggested earlier a little bigger carb could help out I think.
As I mentioned I'm looking for a 750 cfm carb. Do you guys recommend something with vacuum secondaries? Also, should I go for single or double pumper?

camaro355, please read through this tutorial by Dimi Elgin of Elgin Cams. It will lay the groundwork for you to understand camshafts.....

camaro 355 what does stroking an engine have to do with the cam duration? Your last 2 posts on this thread,I dont understand?
do you have any math to go with your statements?
|01-27-2013 03:38 PM|
|camaro355||if you have to much duration its not going to make it run any better unless the motor has been stroked if it has a stock stroke your going to be dumping to much fuel and air into the motor thus not going to run right remember you can easily over cam a motor|

|vinniekq2||camaro 355,using less duration does not have anything to do with the lobe separation angle.|
|01-27-2013 03:17 PM|
|camaro355||sounds like not enough compression for that cam|
|01-27-2013 03:12 PM|
|camaro355||less duration on the cam would help you have to have a tighter lobe seperation in order to make the most power and step up on the carb a little and for the cam i would run around a 274 duration for the build you have going and about a 2500 stall to get the truck going|

Bumping this thread up, I've been looking around at some used carbs because I'm wanting to get a 750.
I've found a Jegs 750 carb locally, that I might can get a good deal on.
Does anyone know which company actually makes the Jegs carbs?

For what its worth, I have the same heads (Sportsman ll's) advertised at 64cc. I cc'd mine and they bang on 61cc's with valves in, no plugs.
