Hey im new to the F-body world and have some questions. I just pulled the engine out of my 96 TA because it threw a rode. (going 20 miles an hour on an on ramp ) Since the engine is out I feel i should rebuild it, but the plan is to stroke it to a 383. The kit that I am looking at now is the Eagle SBC 383 Stroker. I also want the engine running 11:1 comp. I was thinking that 40 lb injectors would be efficient enough for this set up as well. My questions are;

What cam should I be using?
Would it be worth purchasing LT4 heads and I/M?
Are there any other modification that I need to consider for this setup (fuel etc.)?

Keep in mind besides what I mentioned, Im not looking into purchasing any thing else that is not necessary, only what is required to allow this setup to run well.

Thanks for your help.

 

Porting the stock LT1 heads is often the most cost effective way of building HP. But it depends on what kind of HP level you are looking for. So will the injector choice. Start with two things in mind.... your budget and your HP objectives. Then select the best parts to achieve those goals.

Take a look at the ePortWorks LT1 head/cam packages. They include a guideline on the other modifications required. Those or for the stock 350ci displacement, so you will need a bit more flow for a 383. But they will give you an idea of cost vs. power level vs. supportnig modifications.

I took a look at the site. I like the heads they offer. I was thinking the LT4 heads because of extra flow, higher RPMs, and Larger valves. Im not sure what the air flow is on them im going to have to look that up. The cheapest head that is sold at that side had a air flow of 255/180. So i wonder what the LT4 heads flow in that case. I also still have no idea what im going to do about a cam. I have a tendency to over cam lol.

 

Do you know if Elliotts heads come with new valves and springs or is it just port work

 

Yes, they come with all the hardware.

 

i just put on a package from advanced induction and couldn't be happier.

 

Get the best set of heads ya can afford and build the engine around them.
Much to early to talk cam.
Fuel pump,regulator,and injectors are a must IF ya are going to make any HP.

 

Stock LT4 heads flow in the 235-240cfm range, or about 15% more than stock LT1's. So, they are not a cost effective way to increase flow, compared to simply porting the LT1 heads. If you are looking for 300+ cfm, the LT4's are a good starting point, but there are other aftermarket choices.

 

As far as heads go, I decided on the LE2 heads. I am going to talk the company about a cam.

 

If i buy the Eagle SBC 383 Stroker that has 11.6:1 comp and I use a .039 head gasket, not decked, will I have to worry about piston to valve clearance when purchasing a cam?

Also this might seem stupid, but can some one explain this 2 pc, 1 pc deal. I dont understand what they are talking about for the Eagle SBC 383 Stroker.

 

Your motor has a 1-pc rear crank seal.

 

LT4 heads only flow better than STOCK LT1 heads, get a package from eportworks.com and outflow those LT4 heads for the same price I would recommend the LE2 setup

 

Yea I knew i had a 1 pc real seal. (took it off today) It didn’t make since what they were saying in the description.

I decided to buy the LE1 head. I E-mailed Elliott today about it. I am waiting to see if he has a good cam for my 383 too.

Does anybody know if the piston to valve clearance is going to be an issue?

 

no it wont, but you do need to get a small base circle cam. or, get the rods clearanced for the cam...but it's cheaper to get a small base circle cam.

it will be a special order, you will not be able to return it. you will also have to wait a week or so, so you might want to talk to someone about a custom grind. it's the same price, same wait time, and you may be better off. i didnt like my cc306 cam much at all...too much overlap for my taste. and not enough umph.

i had stock ported heads, 52mm tb, stock ported intake, cc306 cam, cc pro magnum rockers, and a scat fully forged RA with hypereutectic pistons from keith black
