Hey guy's, I was just wondering.. whats a better use for my LG4? a paperweight or a boat anchor?
Anyways, I have a 350 that I want to stroke out to a 383, I was wondering anyone's opinions on a good combo to make power. Any recommmend "must have" parts/brands... Also, is it better to buy a stroker kit.. or buy the parts by themselves? Thanks =) The engine is going to be carbed

 

hey if that LG4 is an 86 then i want the flat top pistons/rods out of it

you parting it, or are any of them damaged ?

good luck

 

Yep, it is an '86 LG4.. and nah it's still in the car right now, it runs fine.. when I take it out, you can have whatever you want out of it, just pay shipping

 

My engine is just fine, dont get why people always bash the lg4, they made it for a long time, people are just too hung up on 350s

 

There is no replacement for displacement.

 

Your right 83chevy_camaro... people want to go fast.. how stupid of them =P.. haha just kiddin bud. The LG4 isin't economical to modify, when you look at the horsepower gained by dumping X ammount of money into a 350 and a 305.. the LG4 is a good engine, it made me some decent money.. got me laid a lot and sounds pretty badass with a catback system and headers.. but it's no 10 second motor, unless you dump a lot of money into it. I have nothing against the LG4, I just dont think it should have came in a Camaro.. one thing I can say though, is it is EXTREMELY reliable.

 

tell that to the grand national that would kick just about everyones cars *** on this forum

 

A stroker kit is good because you can't screw it up by mismatching parts. Plus you usually get a bit of a discount by buying all parts from one brand. I'd go for it, a normal 5.7" rod 3.75" cast crank sorta thing.
Go for internally balanced (should be, but just make sure). If no nitrous or blower or anything, hyper pistons, cast crank and decent rods should be fine.


LG4 got you laid? I'd say put it on a pedestal, with a nice plaque below it - one damn good wingman.

 

I just prefer to keep the correct options for my car, which includes the lg4 as the biggest motor you could get, obviously the mast majority want more, i just think original is cooler.

 

I dont actually think it was the engine itself.. but it added..hah. the nice V8 rumble.. to the bright red sports car...that turns highschool girls on faster than a honda hits v-tec

 

..and they have a turbo if i put a turbo on my 355 it would blow past itthe 231 is a smaller engine that has some forced induction. Just like spending money and aluminum heads on a 305 vs a 350. Granted there are some bad 305s but if the same things were done to a 350 it would put out more power. Make sense

oh and have you seen some of these cars on the forum StillbornDevil's 383 will fly

 

Decide on operating characteristics, such as what RPM powerband you're after, and pick the parts to work together. A Victor Jr. intake with an RV cam and 220cc intake port heads is going to be a dog.

 

I dont know why people keep bashing the LG4. Long after that 383 is blowing smoke the LG4 your giving away will be chugging on.

 

It's not bashing, it's realism.

A 5500 RPM 383 will put out power year after year that an LG4 built to make that power wouldn't last through the dyno tuning.

Only if LG4 power is adequate to you is an LG4 adequate.

And I'm no 305 basher . . .

 

How about CarCraft's 6.0L lq4 they are doing. Its displacement is less than that of a 383 but seems to make a fair amount of power for the money. "550 for $4900" I think is what they were saying.

Having an LG4 myself and having a desire for a 383, I can't say too much against the displacement comment.

 

I didn't see that one one but if you put equal parts into a normal 350 casting the output of the 350 would be more. So I think we should all buy 400 sb and stroke them LOL.

 

and then watch them break.

I've seen too many factory 400 blocks built up and then puke guts all over the track to buy into that one.

 

Well you have a point so on to plan B big block time

 

Well seeing as my LG4 smokes now =P..
and yeah.. if I wanted a low powered, reliable engine I'd keep the LG4.. but seeing as my pickup can beat my Camaro in a race.. I think I'll take my chances with the 383

 

Ok, now I have to chime in. My car is a 305 and I get 5 miles to the gallon of coolant. It also smokes and the rear seal is leaking. I met a guy that pro drags 9 sec firsbirds. He built motor for a guy and the guy died. The motor is a totally tricked out 350 with a 350 turbo trans. 0 miles on motor and trans. The guy know what he is doing. Because BIL of friend and he needed cash for a killer paint job, picked up for 1500.00. Now to rebuild my 305 would have been 1500 - 2000 and he said would get maybe 235 HP. Engine Im buying will be around 450. So, it does cost more to build 305 with less results.

 

Use the LG4 for a flower pot in the garden.

 

think I can pass it off as a mothers day present? =P

 

 

I would love to get a non blown up lg4. I've bought three now from local junkyards that were blown up. Sad thing is they wont own up to their lies. It was stated that the motors was good and wasn't bad. Got home and tore it down to revel; Motor 1=cracked piston, Motor 2=collapsed valve spring, and Motor 3=broken camshaft! Now i have at least 2k into the car and it doesnt even run.

 

The lifter valley makes a handy parts tray.

 

So why dont you combine the three to make a working motor?

 

motor two would be an easy fix i broke valve springs a couple times before i bought new ones ten min and it would be good

 

Yah it would, but when your dad stops at your place and takes the motor because he thought they were his to scrap motors, yah now i have no motor.

 

Make a coffee table out of one.

 

I like the LG4 I can have decent power with really cheap mods, and still have gas mileage, Im pushing prolly around 220-240 HP with it and still have my 18-20MPG and with 85k its running like its brand new, not saying 350s suck, cause they are alot better, for performance, but with the way gas is going Ill keep my 305 for another few years until I have a good paying job.
