For the 91 Budget Coupe. Are the factory rods any good or should we upgrade. I was thinking polish crank or maybe turn 10/10 resize rods ,new rod bolts , bore with forged Pistons , and align bore mains if needed. Looking for ideas . Thanks.

Spray? Definitely upgrade, preferably H beams. The stock length 351W I beams aren't as robust as many of the SBC type I beams.

Edit: Stock length Scat and Eagle "I" beams are less robust. Many others are even less so. RPM/Probe "I" beams in stock length with 7/16 cap screws are the exception.

Yep we be spraying. Always. Lol. He will have to stay with the 170tw for a while. H-beams or just some of the cap screw I-beams like Woody uses on his cast crank 408. We have thought about a 408 kit but trying to stay budget. Juice what do you think about 351w ,stock turned crank,some forged Pistons balaced and spraying a 82n jet max. Similar to my 68 mustang but with better rods and Pistons.

Do the 408 kit, internally balance it and be done with it. Stock rods after bolts and etc are wasted money.

If staying with the stock crank, H beams. The 351 I beams aren't as good as the SBC type that Jim uses in his 408s.

I'm collecting parts for a similar build. Stock crank, 6.125 Scat H beams (351W pin size), and 302 domes.

Juice 28oz balance or internal. Didn't know if using a stock block it was worth using a crank that will internal balance..

Unless the lighter pistons/rods allow the stock crank to go internal with minimal mallory, 28oz.

We have a friend here running 5.80s on a stock crank, stock rod with arp bolts and Wiseco pistons on a 250 shot. I would definitely put good  rods and pistons if it were mine.

A buddy of mine in the 90's bought a Coast High Performance 426W that was built with a cut down 400 Ford crank, Chrysler 6cyl rods, and dished Probe pistons in a D9 block.  With a set of old orignial High Ports and a 2-stage nitrous plate, it went 5.92 @ 122 in the 1/8 back then.  It had a C4 and either 3.55 or 3.73 gears.  Didn't need spun any higher than 6400 rpm.  Ran it for a couple years before selling the shortblock.   Who knows how long it ran!  I was impressed with it!  Would run on pump gas n/a! 

Stock parts, WITH GOOD BOLTS AND MACHINE WORK will stand up to surprising amount of power, as long as you don't get greedy with compression, rpm and timing. 

Good Luck!

Thanks for the replies. We are leaning towards a 408 with forged , hbeams, 2618 forged Pistons ,internal balanced.. Or is that over kill in a production block. Would cast rank ,cap screw ibeamsand 2618 forged Pistons ,balaced 28oz be all a production block handle.

If you run cast crank and I beam rods, run .003 on the mains and .0025 on the rod. Cast moves around alot and can easily grab a bearing. Search for gumbys 393 I did

700hp with an 8.2"?  You talking n/a or with nitrous?

Naturally aspirated will take a full effort, and expensive parts.  I'd build a 427W if I wanted to make that kind of power, and have any kind of service life.  Cubes are definitely your friend at that power level.

But, you're talking at least 240 high ports, or preferably Victors...  along with some help from some very talented people.

Good Luck!
