i would recomend a holly but thats just me its a argument between alot of ppl that goes on for a life time lol

Re: Ok guys new idea... EFI need help
 

Looks good to me, but I bet you could find them on CL and save 2-300 bucks. The polish is nice, but unless your engine bay is dressed it wont matter. Save the money and put it towards a 4sp.

Re: Ok guys new idea... EFI need help
 

Go 6.0!!!!!

Re: Ok guys new idea... EFI need help
 

ok my engine bay is dressed up how much extra hp u think all that will make

Re: Ok guys new idea... EFI need help
 

well, you have to add the N.O.S. and k&n sticker to add HP...
I thought everyone knew that.

Re: Ok guys new idea... EFI need help
 

The truck (if I'm right) came from the factory with less then 200 hp, like 190 or something. So I couldn't guess. But I would bet you'd be able to tell. If you are looking for HP then you need to ditch the old heads and just go with that top end kit. Bang for your buck you can't beat it. But you'll get around 10mpgs.

Re: Ok guys new idea... EFI need help
 

Ok so i want to make a list of all the things i will need
-Intake
-Intake bolts
-intake gasket
-600 CFM carb
-new fuel line to replace the qjet hard line
-fuel filter
-camel hump heads
- head gasket ( which type should i buy?)
-electric fan

Am i missing anything?

Re: Ok guys new idea... EFI need help
 

he said he has a 700r4!

Re: Ok guys new idea... EFI need help
 

You don't need the head bolts. You can clean and reuse the old ones. You also want need the fan unless you just want to have one. As for the head gasket, I don't think it matters to much. It's not a high powered high compression engine. I'd buy a cheap set. You'll probably need new throttle linkage, I know I did.

Re: Ok guys new idea... EFI need help
 

Make sure that your camel hump heads have 3x accessory mounting holes. Some of the casting 186, #291, #461, #461x did not have 3x accessory mounting holes (do not remember which ones). On a side note all of these heads have (roughly) 159 to 170cc intake ports with 62 to 64cc chambers. These numbers fail in comparison to any modern SBC head designs. I would not consider (unless it is a restoration job) camels heads since performance & $ spent on ready to run heads just does not add up. For example compare RHS- Racing Head Service 12317-01 vs. what you have to spend on camel heads, machine work and parts.

I went through this camel back head fiasco few years back - wasted tons of money on old castings only to find cracks! End up purchasing three different sets with 4 heads having cracks at exhaust seats which render these castings useless. Installing hardened valve seats was a deal breaker for me. I sold the whole lot to collector-restorer. Caveat emptor!!!

Re: Ok guys new idea... EFI need help
 

so you dont think that the electric fan will do any good?

the camel hump heads do have the accessory holes in them there a good set my uncle said there clean no cracks just need a valve job since they have been sitting ..

Re: Ok guys new idea... EFI need help
 

I agree, stock 350 Vortec heads flow more air then most worked pre vortec heads unless you spend a LOT of money. But like I said, it's all in what you want to do. You could just keep the heads you have install the carb and drive it around until you saved for the top end kit. I know I keep going back to that kit, but I've seen what they can to.

Re: Ok guys new idea... EFI need help
 

he said the heads are 202's even if its a little improvement its free right?\

so no on the electric fan

Re: Ok guys new idea... EFI need help
 

Free is BEST! And they will be an improvement over your stock heads. So go for it. As for the fan, in MIGHT give you a few extra ponies (1-2), but the only way or reason I'd do it is if you were going electric water pump and fuel pump. That way you take as much drag off the engine as possible. That will net you the most power, but also cost several hundred bucks. I've been looking at parts and to do all it'd be around 6-800. I just can't do it at this point and time.

Re: Ok guys new idea... EFI need help
 

A good point has been raised earlier about rear ends. If you have a 4:10 rear axle like me, you will have a hard time getting 15 mpg in a 3/4 ton. I'm just sayin' .......

Re: Ok guys new idea... EFI need help
 

the only reason i said the fan is itd take some drag off and i can remove that big shroud

i dont think i have 4:10 in mine .. i think there like 3.73

Re: Ok guys new idea... EFI need help
 

Bump

Re: Ok guys new idea... EFI need help
 

Before you go spending all the money, you should check to make sure the tranny is going into 4th gear and that the converter is locking up.

Re: Ok guys new idea... EFI need help
 

I'm pretty sure both of those would be something that a driver couldn't miss. At least I hope he would know if he had a gear our or the TQ was slipping. If not the only money he would need to spend would be for a BUS!:haha::haha:

Re: Ok guys new idea... EFI need help
 

I did not say anything about the converter slipping, i said it not locking once it is in overdrive. Which could affect fuel mileage on the highway.

Re: Ok guys new idea... EFI need help
 

If it's not locking it's usually slipping with it shifts. It's pretty noticeable.

Re: Ok guys new idea... EFI need help
 

I guess you don't have any idea what I am talking about, the converter has a electronic solenoid that supplies fluid to a clutch pack in the converter and it only locks up in 3rd and 4th in a 700r4 tranny. Which this makes a direct connection between the engine and transmission, unlike the old trannys like the th400 and the non lockup th350 that only had a fluid coupling between the engine and tranny.

Re: Ok guys new idea... EFI need help
 

tranny is working perfectly what about a corvette servo

Re: Ok guys new idea... EFI need help
 

Look bud, I'm not trying to argue, I do know what you are saying and I don't think that has any thing to do with this. If the converter was not locking it would act up especially when shifting. Been there, fixed it. This is his daily driver. If it wasn't shifting in all gears he'd know, and if it wasn't locking he'd know. That isn't something a person could over look.

So yea I get ya.

Re: Ok guys new idea... EFI need help
 

What about it? Did you rebuild the trans? People install these when rebuilding. Never had one, but a buddy did and I can say that after he rebuilt his 700r4 (he put in a shift kit and servo) the damn thing would snap your neck!

So yea, if you rebuild do it.
