Lil race gas would fix that it was running 89

And about 15 degrees more timing

Yeah see it didn’t make 500 lmao see you proved his point better throw it away and get a 5.3..... kidding of course lol

yea he would make that point.

he was arguing with me that with out bumping compression you cant get more that 475hp even if thats true i personally could round up and be happy. nor would i fault someone for rounding up to a clean number.

he is just one of those people that if you dont do things the way he would do it (he is building a 2jz #noshit taco currently should be fast but still just giving an idea of the stuff he is into. also a honda guy like me. he is just anti carburetor for some reason) then your wrong and could never be right.

I'm looking at a similar question...found a good running '73 454 with a Th400 on it for $700. Told it is a 2 bolt block, stock bore (as far as owner knows). I want to do a 496, for right now just plan on throwing it in my truck and running it till I have all the parts to do my build. Has anyone done a splayed main conversion on a two bolt and if so, was it worth it? (assuming shooting for mid 500 hp)

I was always told a studded 2 bolt big block was good for 600hp and 6000 rpm. Just saying. You don’t have to splay either you can use OEM main caps and have the extra holes drilled and tapped. Now with studsyou don’t want to just crank in the stud for the strongest hold i was taught to drop a small ball bearing down the hole so the stud has something to bottom on to get a proper torque.

I believe splayed is stronger but not necessary if your worried about em moving get a girdle

Yes it is but if your not building an 800+ hp 7000rpm engine it isn’t nessesary

I agreed with you....

Cool, that's what I was hoping...saves about $500 on the build. Thanks guys.
