We started putting a 588ci Big Block together for a local grudge racer its been awhile since we have messed with a big block and never nothing this big should be fun. I can tell you its alot heavier to move around on our engine building table. So far we have set all the bearing clearances cleaned the block up, filed the rings, and assembled the rods/pistons. Waitng on a Kasse oil pump and a piston installer big enough to install these big ass slugs.

A460 Block 4.560 bore
Bryant 4.500 stroke neutral
Oliver billet rods
Ross flat top gas ported pistons
514EX heads the numbers we have for them are 435cfm as cast 70cc chamber
Dominator mafia intake
Lunati solid roller 763/763 288/302@.050 114
Lunati lifters


This is for a back halfed Fox body with a glide. Not to sure on the cam thinking about getting a custom from Bullet done for it. Since he is looking at running 2 stages of nitrous 300 on each kit.

I'm betting the block weighs about the same as a complete 302 Laughing . That kind of stuff is out of my league - cam durations like that blow my mind - huge. Definately on the path to making some serious power. What route are you going on compression? One train of thought is sacrifice no compression and another is on nitrous engines don't go crazy - some I've seen around 10-1. Also how about adding water injection? I'm for anything that makes the tuning window wider. Clay

The compression is coming in at 14.3 to 1 and the plan is to use C16 or NO2 for fuel which helps with that much Nitrous. This is outside what I usually do but the owner has been running similar combinations already. But he has burned them up before also LOL.

Shocked
I'm guessing that setup with the juice should make somewhere in the 1200-1400HP range?

That is around what I came up with (1433hp).
Should run pretty good the trick will be power management on a 28x10.5

That cam is actually pretty close I like the intake duration, it is at the max I would go though. The exhaust is big (duration) and the motor is going to be a bit tricky to get the combo to work well on the starting line. The problem is that you have to run such a cold plug with that much compression and nitrous, that the engine has to be tuned perfectly to not crap out as soon as you let the trans brake go. It will literally drowned the plugs, and put the fire out when you stand on the gas. So you have to run a hot enough plug to keep that monster lit, and yet not burn it up with the power adder. The reality is that he will want to run a 150 hit about .5 to 1 second into the run, and then have the second unit hit as soon as the tire will hold it, probably 2 seconds into the run, and then it will probably only hold 250 more (or less) at that point. It would be easier to split it up into 3 stages, to use all 600. The nitrous needs to be on timers, and the timing needs to be retarded as the stages kick in(also on timers). If all 600 is actually used, the timing will be between 0, and 5 degrees or something like that, or it will detonate. Also run synthetic oil because it has way higher octane than petroleum based oil, and will not cause the engine to detonate on it's own oil when it inevitably gets into the combustion chamber from the massive pressure caused by that much nitrous. I have built a lot of these engines, and for whatever reason the Big Block Fords will take the most abuse (bad tune) and still live without burning up. Forgetting to turn the nitrous fuel pump on, and making a full pass without it is really hard on things. LOL

Funny how small the short block looks compared to the massive heads. That is an interesting jack in the second pic. What is it used for, and where did you get it? Engine looks awesome BTW

It is a motorcycle jack we got from harbor freight it also works great as a transmission jack.

Outta my league! I can say Dad acquired a motorcycle jack and they are very useful. When we were building his 48 it worked great to put the entire k member on and roll it under the truck. The independent rear same thing - you could just sit it on the jack, roll it under and jack it up to the frame without having to balance anything or worry about it falling off. We've used it for all sorts of things over the years and now I'm using it for - wait for it - motorcycles finally Laughing . Clay

Interesting. The heads are canted valved. Not like the standard FE motor.

It's based on the 385 series engines I'm betting which are canted valve originally. I remember seeing I'm thinking a 706" engine at Darlington years ago for sale and I was just amazed at how big everything was. Seeing it like that I was in awe it would even fit in a car heightwise. Clay
