any suggestions or things i need to look out for?
ill keep it updated w/pics

 

ordered carb:
rebuilt edelbrock #1405

 

Too late now, but IMO that 600 Edelbrock carb is going to be kinda small for that 400 engine. I would have rebuilt the Holley you had, it's a 650.
The formula for a determining carb size is: cubic inches x max engine rpm's divided by 3456 x Volumetric Effeciency (%VE). Very well built engines can reach 100% VE, and real hard-core race engines can actually exceed it. So if your engine is capable of 6,000 rpm, and has a VE of 90% (depending on how the heads are built, etc.) then you would want at least a 625 cfm carb. If your engine breathes better than that, or can wind higher than 6k, then even a 650 would be border-line.

 

ok n/m earlier post called and go it swiched to the #1407

your right i didnt even do the math on it.

if anyone wants that holley carb im gonna put it on ebay soon.
just needs to be rebuilt, might even work fine how it is.
PM me ill wait for a few days to list it so i can give CF members dibs if they want it.
also the edelbrock valve covers are going up too.
little bit of rust but my friend assures me we can clean them up before we sell.

idk $40 forcarbOR thecovers to members

 

dang it should be one badass car when you get that 305 out, good call at geting a bigger carb.

 

Plan on keeping those heads???? Going to keep your serpintine belt system???? There are no accesory holes in them old heads [8D]

 

fxck fxck fxck
see thats why i put up the thread
cause i tend to overlook things. that wouldve been the last thing i hooked up too.
i guess im gonna have toget the fancy pants brackets and run individual belts huh.
good thing i got another 5k coming in sept.

good call man.

this is sweet between my friends and the forum im gonna have at least 100 people looking over shoulder on my project.
what do you guys think about the gearing? how long do you think that little baby 3.08 or 3.02 or whatever it is and the T5 will last.

 

Are there any accessory mounting holes on the back side of the heads? If there are, you can swap the heads left to right to put the holes in front. Someone may have done that purposely if they didn't intend on using the holes.

 

That would be some thing new to me. I have always seen heads with holes in the front and rear for interchangabilty between side. Or without on both ends. But I can admit I have not seen everything so there is a possibilty.

 

damn forum probs.
two paragraphs gone.
neway....
no holes on either side
which is better serpentine or individual?
