Post 327/350/400??? which?

I have a 327 I can get my hands on for free.

I've got a 350 I may be able to get for free (no guarantee)

I've got a 400 I can get my hands on for $100 (just the block).

now - I'm building a 1950 chevy truck. I plan on this being a daily driver, but a daily drive I can have fun with. I live at 7,000 feet so I'd like to FI this engine so I can get use of the knock sensore / auto timing adjustments.

I'd like to run a roller cam, and AFR heads. will probably use a holley commander TBI system.

what block would you run, and why? now many cc chanbers would you run, and what cam? how many CFM's should the FI be?

I've heard concerns the 327's don't start moving until up above 3,000 RPM's, and I'd like to run under 6,000 RPM's peak. (assuming that moved me to a 400, or a 350... I'd like to keep decent MPG too)

use the 350 , you will have all the basics to build from, and you can do all that you planned to do with this engine, price is right,parts are relatively cheaper and everything is in stock.

Im with monte, get the 400 block and needless to say the 327, and put the 327 crank in the 400 block and put in some ford 300 I6 rods (6.209 inch long and 25$ a piece) , Send me an e-mail on jakob@regeur.dk and ill send you a buildup article from hot rod magazine on the 350 chevrolet should have built. with the rod ratio (revability and steel crank) of the 327, the cubes of the 350 and the tourque of the 400.

figures from the build; TQ:435@3800 Hp:412@5700

hope it helps

OK Duece - you got me curious, but gun shy... the theories etc. look good, but I've got to ask how proven of a compbination it is? I've been told the 400 design has cooling problems anyway which can be solved by running longer rods, and correct angles.

how is this combination going to work long term? this is going to be a daily driver.

i can send you the article, and tell you the that in theory the longer rods will give less piston skirt wear and give you a motor that is less prone to detonation on todays lousy gas.. and with regards to proven the 4,125 bore short stroke combo works fine for Nascar infact it is exactly what chevy is running, except their parts are considerably bore expensive. but all in all its the same idea

so for reference tune in to ESPN :-)
