ea rod bolts

[Anonymous]

wondering what people are using for EA rodbolts? is it the 289 windsor bolts?

yes, the 302w bolt is the same. when you want to buy arp studs they give you a 302w set so you get 4 spares. cheers

what about for EF rods?

 

[xrglen]

yep the same 5/16 stud and nut but slightly better quality but not as strong as arp studs,,cheers.

Dont Ea';s use a mertic rod bolt so the whesor arp bolts wont fit?

 

[xrglen]

they are a press fit so it does not matter. arp studs come with nuts to suit the bolts as well, so it doesnt matter if they are metric or imperial.
i use 3.2lt 6.27" conrods in my 250 with arp 302w studs and all is fine.cheers..

hi there, thanks for the info.

are you able to provide any more specifics in relation to your bottom end XETURBO?

XEturbo, I am intruiged about the use of chev rods. I just finished writing another post going on about how they are too narrow for the 1" wide crank journal (0.991" swide big end on the rod) Chev is like 0.896" wide from memory.

Did you have the crank jornals welded up and reground or buy unfinished rods or something?

The cranks been offset ground, the conrods are Scat h beam and there are longer than the standard 250units and im using a custom chev piston with a huge dish
