any additional questions feel free to ask
thanks

 

pistons do have a small dome, should be about 10to1 compression

 

shurly someone out there could use a big nasty RAT motor to drop in their third gen!

 

what are u asking for it, are will to look at trading

 

2300.00 we could except a partial trade possibly fepending what you have to trade!
thanks

 

I cant belive no one needs a rat motor, need to sale no reasonable offer turned down!!!!!!!!

 

ya they wouldn't mind if they had money to blow, but for 2300.00 you could put a 350 at over 400HP without the hassel of swapping motors. what year is the motor?

 

show me how to build a 350 with 400hp for 2300.

 

well I guess you could but you would not even come close to the torque of a big block, with less money than 2300.00/ and its no more difficult to install a big block in a thirdgen than a small block if you know witch parts to use, all the info to do it is here on the site/but its your money spend it how you want but dont hate on the guys that want a big block thirdgen!!!!!!
----------
I second the motion!!!!!!!!!!!!!!!!!!!!

 

I'm not hating on BBC's, you can definatly put out a **** ton more power with the 454 than you can any SBC. if you had the money.



these are on a 350 chevy shortblock out of hot rod magazine. i'll give you stock vortec heads and afr 195 heads. these are with different camshafts that would put you at these numbers. these have been tested.
1495.00 for the 195 AFR heads
450+ for the camshaft
These also had headers on them and im sure a performer intake manifold. but in the end you get around 2300-2400$$$

xe268h-10 1500-5500 rpm: 409 tq @4000, 372 hp @5400. afr heads: 420 tq @ 4200, 418 hp @ 5800 rpm.

magnum 280h-10 2200-6200 rpm:403 tq @ 4300, 378 hp @ 5700. afr heads, 422 tq @ 4300, 426 hp @ 6100.

xe274h-10 1800-6000 rpm: 414 tq @4100, 385 hp @ 5600. afr heads: ... didn't give exact #'s. all they said was "afr's head are worth about 47 hp and 12 torque" give or take some

magnum 292h-10: 407 tq@ 4300 rpm, 400 hp @ 6000. afr heads: 415 tq @ 4700, 450@ 6400

283thr-107:418 tq @ 4200, 396 hp @5900. afr heads: 436 tq @ 4300, 453 hp @ 6200

 

with the price of fuel now a days, I am building small blocks 8-1. but a 454 will get moving faster!! The new mark, with todays technology for gen 1 small blocks is 500 fwhp.

 

thats just for the top-end im sure, how much did the article say the shortblock cost to build?

 

Ya, BBC's have a ton of power, i own a 91 GMC 2500 with a 454, i've done minimal work on it and i love the TQ! lol. but you work a SBC right, it will scream like mad

 

sorry i missed the part where you added up the cost of a short block, i pretty sure thats not a stock short block, how about adding $500 for pistons, $400 for block work, good bolts hell maybe even rods and crank

 

stock internals, no bore, no stroke. with that much power i'm sure they added new fuel rails and oil pump etc etc. its advised to redo your block, but when most people think about that, they figure if they are doing that they might as well bore 4.030" over and give it a 3.750" stroke for a 383.
----------
it was stock, you don't have to redo them, if you do its just to make sure they are touch enough to handle the power. wtf? you don't need pistons unless you bore/stroke it or want a different compression ratio.

 

This particlular article was done on a junk yard engine, not even freshened up, just replacing top end, FYI hence the name "junk yard gen 1 jewel" than also the did the same to a truck junk yard 5.3 and got 650hp

 

sorry i never seen a stock short block (8.5cr) makle 400hp without power adder

 

5.3 ls series motor that is a league all there own

 

where did you come up with a 8.5:1 CR? I think in the article it said it was a 10:1 CR. you better get your stories straight otherwise your going to make a fool of yourself.
----------
he's talking about the 5.3L, we are talking about putting a 350 at 400 HP, but either way, ITS STILL A SBC

 

those articles in those mags can be very misleading, You have to remember they get kick backs of the advertising they do, and you really think any of the manufactures that are giving them money, that the mag is going to give them a bad review. Im not saying it cant be done, but what I am saying is I just dont see it happening for 2300.00. also in some of the car mags on the last page or so on the parts brake down, it will tell everything that went into the engine and 9out of 10 times its not what they started the article off with! just my two cents. But any-way this thread was trying to get this engine sold not debate witch is a better build!
thanks

 

you want any 400 sbc parts

 

just trying to make a point, and sure, it might not be exactly 2300 maybe 2600-2700 but either way. sorry for getting off of the subject, good luck on selling the motor.

 

not a big deal!
----------
well I guess ill leave it for sale on here till friday, then its off to e-bay
thanks

 

2 words vortec heads

 

It will take a heck of alot more than vortech heads to make a 400hp 350,

 

just a cam, intake and carb. I wouldn't call that a heck of a lot more. ask me i've done it

 

Then your one heck of an engine builder beacuse I have never seen it done, and spend most of my spare time at my brothers dyno shop and havent seen it done there eather, post a dyno sheet I would like to see it!

 

sgreen, just look around! these guys are pushing 12 second quarter miles with heads, cam, headers, intake, and other mild bolt ons. if you don't believe me just look around!

 

do any of them have any posted time slips with what kind of build theire running, im not saying i do or dont belive any one, but if your going to make claims its a good idea to have prof to back them up, and again how did we get off the subject at had once again!
