i just got done putting my motor together today. it's a 1971 chevy 400 small block bored .040. which makes it a 408ci. heres some pics.

 

another

 

and another

 

and the last shot of the bottom end.

 

Lookin good! What type of induction are you going to use? Carb or fuel inj.? Specs. please! j/k, good luck with it

 

here are the specs. these numbers are from desk top dyno 2000. with the the stock 441 casting heads:

308hp @ 4000rpm
442 torque @ 2500rpm

the only reason im going with the stock castings is because im doing this on a budget. next winter i will most likely be putting aluminum heads on. the numbers with aluminum heads are:

399hp @ 5000rpm
458 lb ft torque @ 3000rpm.

oh yeah im using my performer intake manifold that i have already with my carb.

 

Oooooooooo, daaass niiiice. Very pretty. Who built it, and specs'd be cool.

a friend of my family works at a machine shop. he did all the machining there and we build it together at my house. this way i would save some of money

 

Cool! Are you by Pemberton by any chance?

 

Nice... but thinking you should get more power out of a 400. Putting a 412 Pontiac in my 87 and looking at a little over 500 horse with about 480 lbs torque

 

yeah yor right but i don't have that much money to spend. it will definately be a noticable difference (considering its a 5 speed manual with 373s). its also a mild build up. its got just alittle under 10 to 1 comp. ratio. i wanted it to be a good reliable street motor. i plan on starting to rip my car apart next weekend. i'll keep you guys posted on how things go.


i have never heard of Pemberton. i live in franklin lakes which is by oakland, wycoff, ramsey, ridgewood, fairlawn.

 

Oh sorry, thought you were south from here but you're north from me! Later

 

thats nice! should be nice power, and a nice base to work off of, lots of potential with a 400. did you get the motor out of a truck? all stock with stock cam and eveything? not bad at all imo.

 

kewl but be easy with the clutch or you t5 won`t live long

 

yeah, i don't expect that trans to hold up for a long time. once i get the money i plan on a 6-speed. we will see about that when i get to that point.

i think the motor came out of a caprice or impala(1971)
