Old School help... lets build my 350!!

Personal Stubborness and the need to do everything myself put aside now....

I have a stock 350 and want to build it up into something w/ some power but fairly economical too. I converted it to HEI (full new distributor) and have a new Edelbrock Performer Intake and 650 cfm carb (Part#1406) sitting here. New Edelbrock Elite Valve Covers (tall) are in the mail as I write. What I want for help here is some guidance through the numbers for the motor and where I should go from here w/ the heads, cam, rods, etc. The motor is in a 74 chevy truck and currently runs fine. I don't wanna pull the motor out at this point but would like to possibly change out the cam, rockers, possibly heads....I don't know....someone w/ plenty of experience please help with some good thoughts here please!!





Knowledge is Power!!

headers for sure. If you are wanting a pretty good build up, I would consider using your intake and carb, and headers on the current motor. And in the meantime, I would gather parts to put together a shortblock. Then you could swap out your other parts to the new motor later.

I don't mean to be a pain in the butt or anything, but the 1406 edelbrock is only a 600 cfm carb. The heads, cam , intake, and carb are going to be the easiest things to change without removing the motor. The HEI is a great upgrade. I am not that found of the Performer intake. I personally like the Weiand Stealth intake. Great bang for the buck.

Where am I at with the stock heads? I don't have access to a full fledged shop. What brand of heads would you recommend?? I am not sure if I could afford a high quality set of heads right now. What can I do with the cam and still be able to keep my current heads? Or are they simply not at all applicable for a performance motor?

With the parts you already have if you get a Comp Cam part#12-230-2 which is a XE250H-10 the old truck would pull good and be fun to drive untill you get all your performance parts together and build what you really want.


P.S. make sure you get the Comp lifters to go with it!

I have no idea. I just bought the truck recently. With the grease and grime and some old paint jobs, numbers have become almost impossible to detect without some good cleaning. Where on the heads will they be stamped? I tried to determine the block casting numbers but the only place they are stamped is on the rear of the motor behind the heads. No luck reading them (hard to get in there to see). Gonna do a serious cosmetic job on the motor (while still in the truck) soon. Just waiting for more parts before doing that project but I will be writing down all the numbers when it happens. I am gonna clean/degrease the motor good, paint what I can with it in the truck, new carb, intake, fuel pump, air cleaner, valve covers, distributor. Basically most of the accessories. I don't wanna dive into the heads or lower end at this point. I want to plan on doing a camshaft/lifter upgrade this summer. Also considering maybe buying a short block GM crate engine too. Would this be a more viable option? Also, what are people recommendation on the cleaning/degreasing/painting portion of this current project? I don't wanna destroy any seals/parts/etc but I also want my paint to stay!!

Any help would be great!!

Ok...I haven't even removed them yet...still collecting parts and I don't wanna buy new gaskets multiple times. I will have all the numbers when I do. I am pretty sure that they are your basic OEM stock heads for a mid-late 70's 350 SBC.

I would take back that intake manifold and get an Edelbrock RPM Air Gap for starters.

Ok, ok...what's wrong w/ the Performer manifold? Is it really that bad of an Intake?? I bought this a few months ago and am not sure that I can return it now or not. I don't have high compression pistons or heads but am simply looking to upgrade this old stock dinosaur motor. I think at this point the granularity of it is a little beyond my scope and needs for the moment. On the other side of the coin, I do want to eventually have a block built for me and transfer many of these parts over to it...

Second opinions welcome!

a performer wil work better for your motor than an air gap stick with the performer you put an air gap on there it will probably bog anyway the performers flow great. This may sound stupid but go pick up a K&N air filter it will raise your power some. If you want to make your performer better put a spacer on.

Yeah, I am gonna keep it mostly cause I have it here in front of me now. Upon looking back at my first post in this thread it is actually an Edelbrock Performer RPM intake, not just the Performer model. Sorry to lead ya all astray there.
