The 303 cam is a decent one but if you are increasing the stroke to gentoo 331 think a higher lift cam.
If you are using the truck for a DD you want good torque; a short duration high lift (.510) cam to get all for the power out of the extra cubes and still have the thing streetable.

About the heads make sure you have headers that fit the truck for the heads you will be using.

Also, just an opinion... If you haven't built the 331 yet, stick to 327 ci.

Luck n the project.

y did u say this= If you haven't built the 331 yet, stick to 327 ci.
327 to a 331 is just bore size and he has the larger bore already so it would have to be a 331.
also u know if u go to a bigger motor by stroking it you will need a new balancer and a flywheel

Right miss read the OP.

.040 over ore is a lot for a SBF, .030 is the recommended max overbore.

The flywheel can be re-balanced and the Dampener is sort cash, just get a good one.

Luck

I guess the question should have been before the machining of the block, how many miles were on the block to get a ring wear groove to deep that you had to overbore it .040 ?

Also, the cam, mine is from Comp Cams, i knew I wanted a high lift short duration to get more gas in at lower speeds, more seat of the pants feel. I didn’t want a longer duration cam because the overlap of the valve start to get in there and then there is a question of too much fuel for a street engine.

I do not have the specs for the cam in front of me but will look in the shop to see if I can find the spec sheet.

All I can remember is .510/.512 lift and I think it was a 258 duration and that it is made for EFI; there is something about lope separation difference between an EFI and a Carb’d engine.

What are you planning on doing with the truck/engine after it is running again ?
The way I always approach a cam purchase is what I am doing to do with it, what I expect for performance and how much hp I want.
I contact the Cam Manufacturer Customer Service, most have cam selection groups and will help you out.
All you need is the above questions answered and the weight of the vehicle, mods to the engine.

Good Luck on your choices, it should be a nice setup anyway you build it.

basically a playtoy... i dont know the mileage on it i only paid 150 for it... it had a blown headgasket and the compression ring on #4 was half missing.... soo i just completely gutted it and cleaned it all up and i spec'd it out w a dail bore and it was oblonged a little... maybe .010s... but the ring groove was NASTY up at the top and the crank on the 2 piece rear seal was grooved nasty worse then the grand canyon.. lol
soo i took it to the machine shop and said deck,hone, flux and all

good luck with that.
the 331 ci SBF are pretty good.
I have heard there is a 327 in the works for another Ranger Forum Truck but still waiting to hear how it turns out.

I didn’t read the first post completely so missed the fact that you already had the block bored and when I suggested the 327 I had in mind, the SBC, yes a chevy.
The 327 SBC is what I consider the best small block chevy engine ever made and if you could get a SBF to run the same it would be a very good performer.
When Chebby came out with the 327ci/365hp engine it tore up the streets there wasn’t much that could touch it in stock form.
I build a SBF that could pull first and second against one but that was it the SBC would start to pull in third and gone in forth.

Anyway I am rambling… good luck with the engine.

scrambler sry been out on the road trying to catch up on bills and such... i have the 92 striped and its worse then what i thought.... gotta put it in the shop for new floor pans removed the seats and i literaly pulled half the supports w it and had to cut the sliders off the seats cuz the seatbelt t50s were frozen snapped 3 bits in them.... and snapped 4 drill bits... and yea... im gonna do a custom header panel where i cut the center out like i did to get the 3.0 out i just scrapped it was a good running motor... im hunting for about 350-450 range... stroker kit heres the kit im ordering here shortly... then im wondering on the heads... if the gt40s are even going to clear... and wondering if the e303 is even big enough to take advantage of the added stroke and bore...

I had an x303 on my old hot rod. It sounded amazing and was great at the track, but i don't think it would work very well for a truck motor. Low rpm power was lacking and it depended on a torque converter with a higher lock-up to run well.

Something like an e303 with higher ratio rockers would probably do nicely.

The cam to me should be short duration high lft.
It should help the low,end some but also have enough lift to improve the top end too.

Luck on your choice.

i was thinking to the 1.6 ratio rockers from the stock 1.7s and running a e303 or a f303 im wanting power to come on about 15-1800 and go till about 45-5k and its gonna have a t5 strapped to the back cam specs

I thought 1.6 were stock.
People put on the 1.7 to get more power.
If you have the 1.7 and go to 1.6 you effectively reduce the lift of the cam and reduce the power output.

Best thing, IMHO, is to buy a new cams w/ kit, get a short duration, allowing the power to come in earlier in the rom range and high lift allow the largest amount of gas to get in.
Tis type of cam will allow low end power and decent higher end but there would be a limit in rpm around 5 to 6 grand.

The E303 is a higher rpm cam not a low torque type so you really need to think on what you want.
Trying to get low end power from a cam designed to get higher rpms is not always a good idea.

Look at pricing on a new cam kit, talk to your selected cam manufacturer, tell them what you want to do, where you want the power to start coming in, the weight of your vehicle tire size, etc,etc... They can suggest the best cam for your application.


My latest engine, a '93 based SVO 5.0L, has a cam like what I am talking about, short duration brings in the power at around the 1500 rpm range for some slow crawling and then there is the high lift to gain more power, manufactured by and produced by Comp Cams.
High lift doesn't always mean high rpm or drag racing...

Good luck but if you have to buy a new cam talk to a manufacturer for their opinions.

First let me say that I am not trying to be an A-hole here, just making statements and having you think about what you are going to do with thetruck, what you thing you want, etc.

Is this a 2 or 4x ?

What is your intended use ?

If you are not goin got drag race then think about just how high of an rpm range you want, then ge the cam to get you there.

Next think gear ratio vs tire diameter if you just put in 3.31s, then new gears are secondary so keep the tire diameter in a size that compliments the gear/rpms of the engine and things will work out.

Just me thinking out loud.
Good luck with your choices.
