Im buidling a 350 4 bolt main that i bought of a friend for $100, needs to be bored cause sidewalls are pitted getting it bored .030 over

Just wondering if you guys would like to give me some suggestions on parts to get such as:

Roller rockers
Heads
Cam
pistons

would help if you guys could give me a couple of ideas but no parts that are extremely expensive not looking to spend more then $200 each item except the head and no more then $300-#350

 

Is it a roller block?
I would suggest some vortec heads(valve guides ground down), LT4 hotcam
and some 1.6RR. Should be good for about 350hp. Are you rebuilding the whole bottom end?

 

WHat do you mean by roller block? and no im just getting the crank polished.

 

oh yeah and im gonna be putting the tpi i have on my car now to the 350 and i kno i need the bigger injectors and a chip but will the cam affect that lt4 hot cam or and high lift cam?

 

A roller block has all the provisions for roller lifters. What year is the block you have? if you have roller of flat tappet lifters youll need to get a cam for iether roller or flat tappets. The LT4 hot cam is a camshaft, http://store.summitracing.com/partde...6&autoview=sku

 

its said to come out of a 78 blazer and im just getting flat top lifers and i kno that the lt4 hot cam a roller lifter or flat lifter and im using my tpi off my 305 i am getting the bigger injectors and i chip so i can run the 350 tpi. will using my tpi limit the lift i can get

 

If its out of a 78' then its only machiened for flat tappets, meaning you cant use the lt4 hot cam as its a roller cam. Well unless your willing to deal out 400 bones for a set of retrofit roller lifters. Dont go with flat tops just yet, if your planning to keep the stock tpi, its really going to be limiting you to about 300 hp. In that case freshen up (bigger valves, new valve guides, machiened for higher lift cams) your 305 tpi heads and slap them on that 350. The TPI wont limit the lift, your cylinder heads will. Are you planning on a new exhaust system?
Anyone feel free to correct me if anything is a little off, i dont want 19transamtpi86 getting any wrong information.

 

I have an exhaust on there i just put on in september its edelbrock tes headers, edel brock y pipe, high flow cat and flomasters american thunder series cat back heres what it sounds like if you want hear

Im planning on just getting regular hydrolic lifter and im just looking for a cam that will give me some decent hp. now if i can get theses roller rockers from my friend i am going to put them on. The reason why i am going to use the tpi is the 350 i have came without a intake and if i used a carb i would be settting a whole bunch of codes off threw out the car right?

 

I agree with the 305 heads. The '78 Blazer heads will be horrible.

If you have 1.94" intake valves put in the 305 heads, they will easily support a 350 TPI. While the machine shop has them for the valve upgrade, have them cut the top of the valve guides for positive-type valve stem seals. This will have the dual effect of improved sealing, and more lift capability. Figure on new valve springs (and retainers) if you upgrade the cam.

You'll need dished pistons if you use the 305 heads. Somewhere around 18cc dish with zero deck height and a .040" thick head gasket will put you around 9.5:1 compression, which is what the 305 has.

The Comp Cams XE series seem to work well with EFI and make good power.

The '78 engine will be 2-piece rear main seal, meaning your '86 flexplate won't fit the crank. Get a 153-tooth 2-piece rear main seal flexplate, which would be the '82-'85 f-body V8 automatic application.

The dipstick will also be on the driver's side, but that shouldn't be a problem since you have headers.

Roller rockers are a waste of money in a budget build. Just get some long-slot rockers, or something like the Comp Magnum rockers. 1.6:1 rockers are also unnecessary.

 

Thanks alot that helped how much horsepower do you think that setup will dish out

 

Around 300-320 (gross) with 1.94" intake valves and cleaned-up 416 heads, stock TPI and a Comp XE268 cam.

Step up to a Stealth Ram, probably closer to 360-375.

 

I forgot to add what about the 327 canadian heads? Ive heard from my teacher that they put out good horsepower when you put them on a 350 block. Will they increase my horsepower? and will they work with the tpi?

 

"327 Canadian heads" doesn't mean much. Need casting #'s.

But, since they haven't made a 327 since 1969, and head technology has improved quite a bit since then, I'd take a stab at "no, wouldn't increase horsepower".

 

stealth ram? lol srry im new with high performance and 416 as in 416cc

 

416's - last 3 digits of the casting number of your 305 heads, full casting # 14014416.

Stealth Ram - Holley/Weiand TPI replacement intake manifold. http://store.summitracing.com/partde...5&autoview=sku

 

Would theses be good for rocker arms? http://store.summitracing.com/partde...1&autoview=sku

 

Well, since those are for a Ford, probably not. And since you get 2 rockers for $58.88 and you need 16 of them, probably not a good use of performance $'s.

Like I already said, you don't need roller rockers.

 

Wow im retarted i didnt even pay attention to the ford and the quanity, but i just got back from the machine shop got my block it had to be bored .040 over and my crank needs to be cut. Now he said if i was do do the valve job you said the 1.94" intake it would cost 280 bucks. So he said the smarter route would be just to find vortec heads and messure the clearence from the retainer to the seal just to make sure nothing gets smashed and he would drill out the new bolt patter for the intake for 80 bucks. Casting number on the vortec heads are 062 and he said beware for cracks.

That being said since now im gonna go with the vortec heads does anything need to be change five7kid with your setup that you said to run?

 

Vortecs are a good head. But, the advantages would be negated by putting a "regular" intake base on it. Not only are the mount bolts different, the ports are relocated - the chances of the manifold even covering the ports is slim. Sounds like he knows a little of what he's talking about, can't believe he suggested redrilling for a regular intake.

Get a Vortec base or re-do your heads with the 1.94" intake valves.

Oh, Vortec heads also require self-aligning rockers, unlike your '86.

 

Well when i asked him about resizing the intake valve seat he said that would be alot of work and would probly charge me 280 bucks for it. THen i asked him would you think just getting vortec heads be a better choice, he said well vortec are the way to go theses days but the bolt pattern on your tpi will not bold up you would have to drill in between the intake ports on a slant.

So would it even be worth putting vortec heads on then? if im not gonna get as much power out of them as i would with the modiffied 305s? and if i was to upgrade to that stealth ram would i need to get the fuel rail with it?

 

The Stealth Ram is a great manifold and is available in Vortec style.

The TPI forum would be a better place to ask detailed questions like the fuel rail.

Vortec heads and a Vortec Stealth Ram would make for a nice running combo.

 

alright thanks you helped me out alot for what im gonna do with my engine
