GM small block VS. Mopar big block......

[Revhendo]

A 6 pack is nice and was available stock, but you can do better with an aftermarket single 4 barrel for less money.

Not to mention the single 4 will be way easier to dial in. (For us common folk)

Still haven't heard, does bro get to throw the same amount of money at his motor that you do?

You may want to think about a good plate Nitrous system. but with the addition of a system you have to make sure the rest of the fuel system is up to handling the addition gas flow/supply. This is assuming the rest of the engine is fresh. A 150 shot will wake your 440 up a bit. And always use good Race gas if your spraying the car. There is a lot more too it, but you can find a lot of good published information that will be helpful.

I would add big tube headers,stall converter,391 or 410 gear,and a good ignition system.This added to what you have already done to the 440 will really wake the 440 up.

A few years ago I bought a roll bar for my Bee from a guy that took it out of his 1969 six pack Bee. He told me that one of the most noticable things he did to his car when racing it was to change the 5/16" fuel lines to the 3/8s" lines. You can add cam, carb, intake, do head work etc. but it is all for naught if you don't have enough fuel supply to feed it. I have both 1/2" supply and return lines on my Hemi car. This is a very common oversight by guys that are not really racers and are just entering this arena as they just start throwing parts at it based on recommendations from others.

It sounds like you are looking to keep your car close to stock, streetable, and don't want to spend endless dollars. I would think in fairness you and your brother should set some rules. Maybe a dollar amount cap on what each of you are allowed to spend. Then it is up to each of you as to how wisely you spend your money.

In nearly ALL cases the best bang for your buck before you do anything else would be headers and fuel lines. Then carb & manifold, but that choice will be determined by what internal mods you may dicide on. From there you have to determine what you can live with regarding streetability.

LS motor vs RB

I have experience with both. Don't let the 167k miles on the GM fool you. That really isn't that bad with modern fuel injected engines. They don't get anywhere near the cylinder washdown carb engines do. If he has reasonable ring seal left, you might be in trouble. Cammed and tuned LS motors are incredible. Don't forget that the main contributor to the LS cylinder head development was Tony Mamo. If you haven't heard of him, he is head of R@D at Air Flow Research.
You can see what I am driving, so believe me, I am pulling for you. I would focus on top end pull because otherwise you will have all you can do to hook up on the starting line. Don't underestimate the LS, you will have all you can do to poke ahead of him at the end of the run.


Just my 2 cents

This won't help you with your competition, but maybe it will help you not worry about it. This guy at work has a '31 Ford roadster he inherited. Flat black, red wheels, pie crusts, no fenders or hood, and a Flathead V8. The block cracked, and he spent $4000 on a new motor. Would the car be faster for less money if he put in a 350? Sure, but that's not the point.

 

[wedge5]

The LS out of the truck is not the LS1 it is the 5.3 A buddy of mine has an LS1 GTO and has been telling me that his LS crowd has been taking those 5.3's with minor mods and running mid 10's so don't sleep on those engines. I hate to say it but the chevy would most likely win but there is only one way to find out.Run whatcha Brung!

 

[Revhendo]

Nope, if that motor came out of a truck, I believe they use a LQ designator. But, it essentially a LS motor with an iron block. There is a lot of buzz about using heads off of an Escalade (LQ9?) and upping compression and performance.

 

[5.7 hemi]

Since compression is low, put a huffer on it. I don't know alot about doing this, so do some research and find out what you can. Our 01 Tahoe does **** and get, but a 440 with a huffer on it should do the trick and take home the prize.

 

[Revhendo]

LOL, put a Magnuson Supercharger on that Tahoe, you could probably give that 440 fits....

 

[dantrap]

A few guys in WNY are using the Pro charger setup with an intercooler here in W.N.Y. and making a lot of power on the LS1 / LSX engines. So much I would not even post it here, because if you have not seen the numbers you would think it was possible.

 

[5.7 hemi]

Thats the family car, so no messing around with it, although.....

 

[Revhendo]

Oh no, we aren't talking about messing with it.
We are merely suggesting ways to improve the efficiency of the family wagon for economy and safety.....

 

[69Chrgr]

I agree with a previous post as your old 440 is apples to his oranges. With that being said, the 5.7 Gen3 Hemi with the same mods would be more appropriate. If you need that house payment, send his happy *** down here and he can run my stroker smallblock 68 Cuda with change to spare.:yes:

 

[hemicop]

Asssuming the rules for your "match race" is stock parts, no INTERNAL mods, or power adders, you MIGHT have a chance. If it were me, I'd lighten your Mopar up as much as possible (DON'T tell him!) and try to get as much torque out of it as you can. Don't try to out RPM him as you simply ain't gonna do it. I've raced Chevys for years and in the last couple of years switched over to Mopar & am amazed how many guys think they can out-rev a SBC---- you ain't gonna do it, especially with a big Mopar! You need bout 550-600hp around 6500RPM or so to make this a winnable race (IMO) and I really don't think you're gonna do that with bolt-ons

 

[69Chrgr]

Just because you can "Rev it til it Rains" don't mean you're still making any kind of power at those levels either. The good thing about Chevy guys is they are almost ALWAYS over-confident that their Camaro or Firebird from the local trailer park is invencible. That is what's fun about handing their @$$ to them.:yes:

Agreed.

 

[moparman9]

Hi guys im new and i was reading through this... is there anything in your bet that says you cant have forced induction? cheep power = turbocharger... just a possibility

 

[joesnow]

What do I know, but he we go.
What if you:
get some big valves
porting
cut the heads down to up compression
maybe switch in some old HP magnum pistons
soild cam
RPM intake
750 DP
3k stall
4.10
headers/duals/x pipe
valve body in the trans
SS springs/ drag slicks
race front shocks,longer rear shocks
3/8" fuel lines/ HV fuel pump?
Lighten up the car
no heater/no spare/radio/lighter
wheels/glass hood/bumpers/
diet
Good luck, sounds fun. But you have to take every advantage.

Woah woah woah. I'm all for hating on Chevy's, but the first generation Firebirds had Pontiac powerplants in them. Don't drag a Firebird into a Chevy/Mopar fight. and the Pontiac owners had more class then to live in a trailer park :grin:
