good combo for a lightweight vehicle

[fitzwell]

Planning on a roller 306. Have a set of stock E7's, also a set of windsor jrs. This will be going in a 46 pickup with an overdrive & 3.73 gear. Max HP is not a concern, this thing wont hook if it's life depended on it. Truck gets driven on an almost weekly basis, and we make long hauls, 500-1500 mi on occasion. What i need is something that has real good throttle response, and will pull hard from a rollng start.....
Any input appreciated, smartass comments always welcome :jester:

well I wouldn't even consider bolting the E7's on since you have some windsor jr heads. Look at mild cams. (E303, maybe the crane 2030, etc)

Is this going to be a carb setup or are you going to install fuel injection?

Still getting used to the whys & wherefores of the Ford EFI. Will have both of my trucks converted by the spring of '06 ( 69 f100 351w & 46 1/2 ton 5.0). . .


:D

injected ..have the setup off a 95 GT. Was planning to use the jr's on my 69 351. at 4200 lbs it's gonna need all the help it can get. Will the E303 work with the stock pistons? As i stated, this does NOT need to be a max effort motor, just a little something for the guys with the 350 / 350 combos in their early chevy trucks ;)

Will the E303 work with the stock pistons?
Yes, as long as they have reliefs in them like the 87+ pistons. I'm running an E303 with 1.7 rockers on a '91 stock short block.

If your going to use the stock 95 GT intake manifold, I don't think I would go bigger than an E303 sized cam, as I don't think the intake will flow much more than theat cam will want, let alone anything bigger.

If you have the money for it, take the E7 heads and have a 1.86 intake and 1.54 exhaust valves put in. When this is done have the machine shop do a good 5 angle vale job, and open up the bowl are just a little bit.
The stock heads in the exhaust runner have the emission hump, cut this completly down, also do a port match on both the intake and exhaust.
Lastly cut the heads even, just take a hair off of them.

I would think that with this minor head work, the E cam you should be able to see around 240-260 HP, I had a similiar combo with a carb. and it was in that bal park.

For the way you are looking at running this truck (using it as a truck), I would suggest going for a cam with some nice low end torque built into it. Something along the line of the 93 Cobra cam, or even the stock cam.

I know, everyone thinks the 93 Cobra cam sucks. Well, it was made to boost torque at lower rpms, and you will be glad you have then when it comes to hauling loads and making trips across the country.

Ported E7's would be nice - they'll keep nice air velocity at low rpms and not have the big ports of the windsor juniors. Also, their peak torque/HP rpm range will be lower, which is what you want in a daily driver. Plus with a mild torque building cam, those 500-1000 mile drives will be much more enjoyable without the eec fighting the damn cam all the time...

thank's for the input y'all....now it's off to the garage & start building :D

I think the E-303 cam and the Crane 2030 are the same Cams aren't they? Either way, I wouldn't have a problem using the E cam and advancing it 2 degrees with that setup. It would make plenty of torque with the setup you mentioned. I would use the Jrs if you want more HP. If you are after torque, then a ported set of the E7 heads would work very well.

The first complete engine setup I had on my 3340 lb Mustang (back in 1995) was a ported set of E7's (1.90 intake, 1.60 exhaust valves and thermactor bump removed), an E-303 cam installed straight up, extrude honed stock EFI manifold, 65 mm throttle body, 75 mm bullet mass air (19 lb cal), MAC 1 5/8 headers, 3.73 gears, MAC under drive pulleys, stock 1.6 rocker arms and a stock T-5. The car went a best of 12.8's@106 and was GREAT on the street. You could blow the tires off at will and the torque was VERY fun on the street.

Had I known then, what I know now about racing, I think I could of done better. The only thing I will say that you should be aware of is the idle issue with the E-303 camshaft. You will need to get a idle air bypass plate that bolts right on to the EGR/Throttle body (Mustangs Unlimited and Summit sells them for about $20 or so). You can adjust your idle with it nicely. It is much cheaper to use than a aftermarket tuner but not nearly as efficient. It has two allen wrench bolts that you adjust in or out for idle quality after you bolt it on. If you have a TwEECer or something like that, I would skip the idle air bypass plate and use that. I still run one of these plates on my car today along with the TwEECer and it works great.

Good luck. Your truck ought to work very well for what you are wanting it to do.

Hmmm, I've been running an E cam for the past 2 years and never had an idling issue. :shrug:

From what I've seen, it's hit or miss...

[fitzwell]

k.o. now for more questions. Seems as the E7's wtih some work will do what i want, now, how about the 1.7 on the exhaust, 1.6 intake trick. Once again, this is NOT a max hp motor, just a real responsive 5.0 for the bowtie boys :jester:
Will the stock HO injectors flow enough, or do i need to step up to 24 lb units?
On the subject of the mass air unit, can i use a stock unit, or do i need to step up to a 65 or 70 mm?
once again, thanks for all the imput

[93Cobra#2771]

19's should be enough. An upgrade of the MAF would be a nice addition...

[One_live95]

i made decent HP with a wacked out a/f and ported e7's with my b-cam..... and the e is a little larger right, so i think you should be ok....will make a lot of torque..i made over 300 rwtq...Oh that was with a ported stock intake as well...

With my stock 302 with ported E7's, 95 intake, F-cam, and 1.6 rr I made 260rwhp and 290 rwtq all with out tuning or anything so there was more in it.
