I hope you caught the sarcasm in my post. The van engine I built for my 84 put out ~330hp @5600 and 320 ft/lb peak torque, hell it was making over 120hp at 2000rpm..

naw didn't catch it lol a few people have said not to use the 4.3 but I thought it was a good fit what did you do to your motor

Codysv6rx7

Old motor and tranny pulled if you look at the oil pan that's why it's the old motor and it blew up on I-5 north doing 70 fun stuff

Painted under the hood and engine bay budget style and got the new motor in

Team_Gileto

Should've pulled the struts before painting

Codysv6rx7

I'm replacing them so I just left them in for paint until I get the new fronts

Wow. Motor looks like a good fit. How about the exhaust? Can you use the stock manifold or will you have to customize something to make it work?

i'm rather surprised, the 4.3L doesn't really have a lot of aftermarket support aside from components that will work from a 5.7L SBC.

they're not exactly rev happy engines in stock form.

In 1996 GM came out with the L31 vortec 5.7(350) it was the last of the gen 1 SBC. They changed the intake and exhaust ports to an improved LT4 style. Guide to retainer clearance is and issue when using a higher lift cam. The change carried over to the 4.3 in the same year. The L31 vortec heads have been know to support 425+ Hp.. so x 2/3 is what the 4.3 is capable of.

you mean 3/4.

Codysv6rx7

just a few mods and it fits like a glove and only problem I have with this motor is the clearance with the good I have to cut and make vents so it will shut

Codysv6rx7

my engine is a 94-95 non vortec that I converted to carb I don't know much about this thing so anything you could help me with would be great I'm just running it stock for now I have a bigger cam for it but I don't want to put it in till I know what It will do. thanks for the help and support for this build everyone!

don't starve it of oil or it will spit the rods out.. don't spin it over 6500rpm (Mine fuel cuts at 6400)
I run a 10% Melling performance select pump stock pressure.
Pick up is ~5/16" off the bottom of the pan.
ARP rod and main bolts.
Balanced to a 50% bob weight (need lighter then stock pistons to achieve this)
3/4 grove mains helps get a little more oil to the rods.
.0025 (up to .003 is fine)main clearance.
.0025 rod clearance.
10w30 in what ever brand..
You can also fill the block to the bottom of the front freeze plugs. I also never go over a .030 over bore on anything.
Find a 3.636 R&P out of a 80s rwd 626 5spd..

One other thing, set your pinion angle at ride height to match the output angle. Make sure the working angles of the u-joints is between 1-3° (closer to 1° if your really going to spin up the drive shaft)

Codysv6rx7

thanks for your help I'm new to this kinda stuff I just drive

Codysv6rx7

New goodies for my fb

Codysv6rx7

David Rodak
