soo, its time to start ordering parts and get ready to rebuild the 410. but still undecided on a few things, like the appropriate compression ratio, pistons/rods, rockers, and so on.
really just lookin for ideas and opinions at the moment.

i have allready done the performance bolt ons, name it it is probably there, or at least under my bed.

so first big question: compression ratio! what to shoot for,what i dont want to go above.
running pump gas is a must.

truck is a 4wd f-100 will have 33" tires. no towing, just playing/ daily driver and some more playing!!!

 

What parts are you thinking about ordering

 

Since you said pump gas is a must, I'd say the CR needs to no higher than 10.5:1, or you could run into pinging issues. Even at 10.5, you're going to need the timing curve dialed in just right.
The good news is, stock 410/390 truck pistons will get you into that ballpark on stock 390/410 rods.

Going over 10.5:1 CR can be done, and keep it on pump gas, but it usually needs the upper end stuff.

 

Stock 410s were 10.5, so your head gasket and cc volume, and IF those pistons are made the same will determine what you end up with.

stock rods and pistons will be replaced with new parts, probly from survival motorsports.
pump gas is only important cuas i drive my truck everywhere. have no problem running 92, or what ever they are calling high test. it is actually prefered

 

ok so at the moment i am looking at
Probe pistons about 10.4:1 (30 over)
Scat H-beam rods
Comp cams XE274H
Holley off road carb, 670 or 770 cfm... still undecided

oh! rocker arms i forgot! roller or not???
i donthave any experience w/ rollers, are they reliable? who to stay away from, whats the best choice?

should i look into a new flywheel? or is the old stocker just fine?

 

Do you have a 410/428 flywheel? They have to be externally balanced.

 

ummmm i would assume so, the original 410 build was done back in the 70's according to previous owner.

 

Oh, I thought you were starting from scratch.

 

What are you using the truck for? If nothing serious which it doesn't sound like the H beam rods are a high, but unnecesary, cost. Rollers are also nice but for most engines also unnecesary. Will probably triple or quadruple your valve train cost.

 

Roller rockers are not a must in my opinion as well. As for carb definitely go with the 670!!!!
I had a new 770 TA on my 428 with similar parts and compression and it had a major top end flat spot where it lagged. Holley tech said the motor I had was too small and didn't have enough velocity to pick up the ball in the metering block. Even the 770 comes with a 2.5 powervalve setup for an extreme cam.
They suggested a 670 and now it's a whole new animal. Good power through all rpm range.
Good luck!

 

I concur. Unless you're going to winding it pretty tight, the H beam rods and roller rockers would just be bragging rights. Costly ones at that.

 

BUT by the time I had mine rehoned and arp bolts put it it was almost as much as H beams. I was mad at my machine shop for starting the build without my go and had entire rotating assembly balanced with the stock beefed up rods redone. I seen cost on rods and was going to put on hold for new ones but they jumped the gun!

My stock ones should be fine and the shop took a few hundred bucks off bill

 

i use the truck for everything, but i have a power addiction, i allways need more!!! and want to be able to turn high rpms if i wanted to.
H-beam rods are like security man!!!
as for money, i dont mind spending it, allways make it back.

 

ya know, that 445 kit from survival is starting to tempt me... cant go wrong w/ another 30 cubes... but is 30 cubes worth almost another G on my build?
