Well, then I'll just have to accept that and make the best of it. Now you have me back to leaning towards the 320. Is there a particular maf that is commonly used for this upgrade? Just don't want to get stuck with something that won't work.

 

Any MAF will work you just need the transfer function for it. What size meter is on the truck now?

 

Factory stock unit is what's on truck now. I found this one on Summit: Delphi AF10115. Will this work? Or will I need a different housing?

 

If it's worth it is relative to the owner. Are long tubes worth it vs shortys? Are ported heads worth it? Compression bump? If I'm the one you're asking, the answer is yes to everything including the extra lift.

 

On the edge of my chair here, what do ya think?

 

This thing keeps growing. I will be going .030 over and looking to increase CR to somewhere between 9.5 to 10. I'm also kicking around stroking to 331 which will add some low end torque, but not sure what the cost difference would be compared to just going to 306. What other costs would be incurred with the stroker build? Just want to explore options before pulling the trigger and getting past the point of no return and wishing I had done it differently.

 

306 is just an overbore, with a stroker you would be replacing the whole rotating assembly and if you're doing that then just hit the reset button and go find a 351 to drop in.

 

I know 306 it's just an overbore, but I do want to reuse the existing block. I know the 351 is a lot stronger and has a lot more potential but also adds a 100lbs and will share the cost of rebuilding my 302 but also have the added expense of buying it. To that end, just curious as to the cost difference between the 306 and 331. Both will get me to the 300 hp level, just trying to establish if the added cost of the 331 for the torque increase is worth it to me.

 

What he said...which would be WELL worth it in that little truck. You could go 347 with the 302 block, the 5.0 truck intake is petty damn good, whereas you'd have to buy a pricey intake for a 351 build, as the 351 truck intake is garbage.

 

Seriously consider this option.

 

Stroke it and don't look back, 302s belong in cars.

 

Parts collected so far:
Rebuilt GT40's
Scorpion 1.6 rockers (arrived today)
Head, Valve Cover, Oil pan and timing cover gaskets
Arp - head bolts, intake bolts, valve cover bolts
24# injectors ordered

Waiting to order cam/timing chain/gear combo and maf until I get more help with selection.

Still need to order oil pump.

So, if stroke it, I will still be cleaning the bore to 4.030 and also adding new rods and crank?

 

Yes, stroker kit will be a full rotating assembly. If you don't plan on boost down the road, get a cast crank and pistons...you won't need forged with rpm as low as you'll be.

You can find a cheaper kit, but can't really beat that price with forged pistons

 

I don't know what a 331/347 stroker kit costs these days but it's got to be around the $1k mark and I don't see a rebuilt 351 shortblock costing anything close to that.

 

Oh I'm with ya on the 351...I was just adding that added intake costs offset some savings of a 351. That, and he said he seems dead set on using his 302 bloq.
