Sorry, I'm too old to remember.

I am surprised at no apology or atleast ,no no no ,I did not mean that !! Completely ok with offending others. And then brazin enuff to ask for more info Kinda like the kettle callin the pot black,then askin for some soup out of it!!

In case you forgot . . . or didn't read . . . here's an instant replay.

I just want to have one of the fastest small blocks around and want to know why some old man tells me . . .

Those kind of comments result in "some old man" NOT telling you what he's learned in the last 20 or 30 years of engine work - which is probably longer than you've been alive - and letting you build a boat anchor on your own.

Dude, where'd you get your manners?

Pat you say you are 43 and an "old man" or so someone else says. Me 48 What does that make me ?


just a word of advice Firebird, that phase that you used offended some of us "old men". Maybe you did not mean to, but just step back for a while ... please.

firebird firebird firebird ................

BigTruckDriver has the right idea. I only know I'm 68 when I bend over a lot and my lower back screams NO! I have solved this problem by using a folding CHAIR in the garage and I do about 80% of my work on the car from the CHAIR. The only problem is working under the frame; the car is too low for a dogbone roller and I can barely get my head under the chassis unless I jack it up and put it on stands. That is when I realize I am not 15 anymore, BUT ( ! ) some of this stuff like a dropped front axle and a chopped top (roadster canvas) I have wanted obsessively since I was 15, so amazingly I am still having fun. I have built only a few engines and am a novice on the SBC, but Rumrum has won the 450 HP prize with the specs of his 383. Sometimes I wish I had built a 383 but the factors against it were:

1. High test gas over 9.5 CR.

2. Low mpg using large head port volume.

3. Wear and tear on the drive line (I have a history of trans abuse).

4. Windup bog using a higher than stock stall torque converter.

Sooooo, I am old, Rumrum has the answer and BigTruckDriver has the right attitude but usually we have fun on this Forum with good-natured jiving. There is quite a history of newbies starting off too fresh and getting a lot of folks in an uproar, but let's not let this happen with Firebird; let's just understand that he wants to go fast with an instant answer about how to build his engine. I am not offended to be called an "old man", actually just thankful to be in relatively good health at my age. I guess if gas was still $0.259/gallon I would have built a 383 too. I have offered two sites with dyno info and Rumrum gave "the answer", now I think Firebird has enough information if he will just study it and maybe buy one of David Vizard's books on the SBC. For the short answer I note that Summit has one answer with a GM Performance ZZ383 Crate engine rated at 425 HP at 5400 rpm and 460 ft. lb. at 4500 rpm for a mere $5139.95, but that is not 450 HP!

Rumrum can you give the specs on your driveline, trans and rear? Dare I ask what mpg you get with that awesome setup?

i think i can help here sell your 350 and build a 638 that will run on pump gas NO NOS NO blower and just happen to have more than one block that can go this big 780tq . this will find the weak link. i know this first hand . and no hi rpms just god awesome TQ

My mechanic, who is an excellent transmission builder, put together a strong 700R4 tranny with hydraulic lockup, and I'm using a 2400 lockup stall converter. The rear end is a Currie 9-inch and the center section is a Detroit True-Track limited slip with 3.89:1 gears. I can get 19 mpg on the open road if I maintain a light foot.

Rumrumm, thanks for the info. I also have a 700R4 built by Monster Motorsports with a hydraulic lockup. It is the intermediate level buildup for the street. I guess my weakest link is the 8" rear although it was rebuilt. Probably I have been too cautious; I could have bought a 383 crate engine locally by a company which has since gone out of business but did not because it required 93 octane. So there you go Firebird, old men who have been through a long period of financial limitation and a record of destroying transmissions tend to underbuild! Rumrumm, that is truly an amazing setup! I guess the 700R4 helps with the mpg. Again, I opted for a 3.55 rear which is probably too high, but at this point I just want to finish the car and get it on the road where I plan to use it on Interstate highways mostly. Well Firebird, Just write down Rumrumm's specs. and start collecting parts because that is one top notch setup, but your Firebird is probably going to be heavier than Rumrumm's coupe so maybe you will have to strip the interior.

Don,

that 3.55 will act like a 2.49 in overdrive. You'll get decent gas mileage . . . and a heck of a kick in the pants in low gear. In low gear, that 3.55 will act like a 4.30 behind a TH-350.
