Oh alright lol I was told it was a 600. Thanks for letting me know.

I will just order the kit. Its proven and made to work together. 375hp and 400lbs ft of torque is awesome. Also already have exhaust done. It is meant for my carb. It is also cheaper to buy the kit with proven results then put together a random one, cost more, and hope they work together.

 

I think the only difference between those two heads is that one has straight plugs, and the other has angle plugs. What makes you thing they come with pushrods?

Yea im just going with the summit kit.

 

I would like to point out a few random things that may help your decision:

1.) If you look at that Car Craft article I gave you a link too, the one that compared the different heads, you will see that the kit you are thinking of buying uses the same camshaft and heads that they use in the test. Your engine will be very similar to that engine, just with less compression. Might give you a better idea of what you are getting into.

2.) The intake manifold provided in that kit will not take a Q-jet. You'll need to buy a square bore carb. A cheap way out of this may be to look for an old Holley 3310 (750 CFM vacuum secondary) and rebuild it.

3.) Here's a tip: Look up the individual prices for each component of the kit, and add them together. It might end up being a little less than the cost of the kit to order each piece individually. Summit seems to think that, instead of giving you a package deal, they should charge you a little extra for the convenience of the kit.

4.) The head gaskets that come with that kit will not be .015" thick. Probably more like .042" thick. There goes about a half a point of compression, which you will need for that big cam. Plan on spending a little extra to get the thin head gaskets, they'll be worth it.

5.)Speaking of cams, I think that cam is a little too much for what you are looking to do. You'll need a higher stall converter, more compression, and more gear out back for it to work well. This kit may be a better option for you:

Ah ok so a couple of questions. On the 25hp less one. I knew about the intake problem but cant i use

my stock intake manifold? And yes I will use the felpro gasket still.

 

Sure, bolt the crusty old cast iron intake back onto you nice, shiny new aluminum heads. Why not?

Scott

 

Ill just order the without the intake manifold and buy a 2101 intake

 

That's right! You can order each piece individually! Did you add up all the prices, and compare the total to the kit? Just not buying the intake should more than pay for a used Performer. Ahhh, but you won't get the free pushrod length checker...........

That looks like a pretty good deal, there, man, good luck with it,

Scott

 

I can actually tell summit I want the kit with no intake and they will take a little off

 

If your set on using a 750cfm carb with that top end kit.Check out the new Street Demon carb.It will work with a square bore manifold and has small bore primaries ,vacuum operated secondaries adjusted by spring tension.The triple stack primaries should give you good throttle response down low for street manners.http://www.demoncarbs.com/Types/Street%20Demon.asp

 

I am ordering the 600cfm one. Using a different head gasket and intake manifold. Thanks though

 

Really? I didn't know they would let you do that. That's pretty cool.

Scott

 

Yea ive done it before. I just hope they do it on something so big. Well see. I asked them about it. Ill let you know if they can take it out.

 

Did you check out the link I posted for the 2101 for 50 bucks? I'm still kind of curious why you thought those heads came with pushrods, maybe we can clear up a misunderstanding of some kind.

Scott

 

No I never saw the link. Could you put the link up again?

Also i thought they did because there site said everything else needed is rocker arms and a gasket so I just though they came with pushrods. Or else they would of said and you need pushrods.

 

so what if I went with this.

intake manifold: 2101 intake manifold from forum user

rocker arms: http://www.summitracing.com/parts/su...make/chevrolet

would this be everything? puts me at $1000

 

I thought I posted it here, might have been another thread. Anyway, here it is:

Yeah, I've never heard of heads being sold with pushrods. You will find that, in this hobby, most people selling things assume a certain level of familiarity with the product. You can't make assumptions like that. Forums like this are where you go with "dumb questions" like that!

Scott

 

Did you see my build and links? Its all $1000

 

you'll need a gasket set, obviously, the pushrod checker and the checking springs. Small change, but you have to account for it all, or else it starts to creep up on you. You'll need tools, supplies (oil, coolant, rtv, gasket sealer, beer, etc.)

Now what you need to think about is what can/should be done, as long as the whole thing is apart anyway. You are going to have to remove the fuel pump and fuel pump pushrod, so you should think about a new fuel pump, fuel pump pushrod, and rubber fuel lines that connect the fuel pump to the hard fuel lines. (there is a good chance that you will destroy the 35+ year old rubber fuel lines while removing them.) Another thing to think about, is the fact that once you have the whole front of the engine off, it's not that much more trouble to break the center link, drop the oil pan, and replace the oil pump and rear main seal. Maybe even drop a main cap and take a look at the bearings. (the number 1 bearing will tell the tale, as it's the farthest from the oil pump.) then seal her back up with a Felpro one piece oil pan gasket. Another benefit of doing this, is that it is easier to get a good seal between the oil pan and timing cover, if you install the timing cover first, and the oil pan second. None of it is mandatory, (although I would almost consider the new fuel lines mandatory) but it's all a really good idea, "while you're at it....."

yes i will have all the gaskets I need. Also a mechanic friend is doing it. He realizes that the engine will have to sit while we order pushrods. He has all the oil, lube, sealant, and tools needed. So he said while we are in there he will tell me what else I need to order and it can sit for however long it needs too. Getting my recurve kit in monday. Will get it in asap! My cam and lifters are coming in tomorrow. Also ordering my timing chain and intake manifold w/gasket next week all that is left is heads, rocker arms, and pushrods after being measured. Thanks for all your help man!
