I dont know but if this was my build I would start with car get one that runs so dont have sit in a buddy shop go ahead and fix all the weak points in car because dont care what car you buy with 600 hp you will be replacing stuff axles gears tires shocks suspension drive shaft you not just going drop 600 hp in and go wish it was like that but all you going do is smoke off some tires and still prob get out run by ur neon if you want the motor to be 600 hp.with 200 to 300 shot and stay together it will cost more than 3500 and I would never. Put 300 shot on gm block I would be using dart I have seen what happens when one comes apart with 200 shot and it wasent pretty can only imagine 300 just my 2cents and there is a lot of hidden cost to a motor like that also with timing box to retard good trans for that power nitrous stall big carb by time you done you will have more in the car than you think it happens to use all.

We run 114 race gas when we use the bottle on our BBC 632. But a clear understanding of how hard nitrous is on parts also come into play.No way do we run the bottle from over 2,500 out the back door.In fact the button and how long the nitrous is run is on a timer.Mid lap using nitrous of only .002 netted in the 1/8 4.50's@ 150 mph in a RED.
I disagree it's hard to play catch up.In my career I can tell you a number of times I lost to being mph'er.

I totally agree with Cobalt in that 800 hp on a stock block is risky best case or not.

20 yrs of 9.90 racing where N/A was used with a glide/brake.Those launches are as hard or harder than nitrous.Pretty much all strokers.Good friend of ours lost his good engine early in the season.Forced him to race a cast crank engine.He held his breath on each launch for the whole season.That thing was a grenade with the pin pulled.Torn it down at the end of the yr and junked it.It was trash.

Point being is we shouldn't advise guys of our high risk adventures many of which have only enough money for the one engine they are asking about.Thing with that high risk is then it is much better to be "lucky" than good.The idea of what? At first stated 800hp and then 1300 hp on a stock block/cast crank is just not logical.

This is a stratagy mistake... make the car hook right from the starting line. launch the car at a very high rpm to avoid nitrous shock. Over torqing the engine, bending connecting rods.
You could have covered the 1/4 mile qucker, using a smaller shot all the way down the track.
It's hard to play catchup.
Sorry i should have specified it was a street car. Spraying on street tires on the street out of the hole isnt an option. Doing that would just send it directly to redline faster then a street bike revs up. A smaller shot would have helped for the first couple gears but the top end really did makeup for it. I remember racing a moderatly modified EVO. He destroyed me out of the hole and at about half track i went by him like he was standing still.

Cause it will come unglued. How many of those are you gong to build and keep smiling?

Yep, i am doing my best with what little i know and the machinist to get it right regaurdless of the fact that im putting expensive parts in it. He said he is going to bore it a tad more then typical to make room for expansion for one example.

The machinist is very adamant that i use H beam rods for the power im looking for.

If i get away with 2k in the bottom end i think im lookin good. As some have said previously its not going to be cheap for what im trying to do. Its looking like a $5k motor on a good day. Its ok though. I know what i want, and im going to make it happen the best way i know how.

I can tell you now I got bout 600 hp and I will smoke slicks on the street at times the street no where near as sticky as the drag strip on street tires I can smoke them at 45 mph no problem and that can get real bad real fast if you. Dont know what your doing or car does something you not exspecting it to do thats why I wont run any street tire I use drag radials and you cant always trust them on the street. You never know whats on the road between oils and other fluids. And water. Im beginning to wonder if you really know what 600 hp all about might not sound like that much but on street its more than most people need or should have

Get some tires that have traction. The M/T ET streets work real good. Its not worth dieing over.
Motors are replace able. If you make a boo boo and smoke a low buck motor, who cares... Stay save.
I was running falcon azenis not 500 treadwear tires off grandmas oldsmobile. Only time i had an issue was when upon turning around to line up my right front rolled through some dirt. a weak burnout didnt clean it well enough. launched and was steering left and still turning right towards the shiny ZO6 i was racing so i had to get out of it. I thought for sure i broke an axle. took me a couple days mentally playing it over to figure it out. A better tire would have only made it a worse case in that situation.

You can get killed 1000 different was street racing. This is why i dont recomend it. We were all young and dumb.

The machinist does have the pistons in hand for the final bore/hone.Right??. He needs that. With forged pistons be prepared to hear cold piston slap on the start up until the engine gains some temps.

I would never run a 600+hp nitrous car on the street unless i was able to sweep and prep the whole road and the shoulders were a relatively safe exit if i lossed it. Oh ya, and the police were fine with it. Im not putting 7k into a car to have it towed off to destruction. Plus im sure thetes some jail time involved these days. no thanks.

Yes he will have the pistons for final bore. Hes seeing if he can get a good price on parts for me as of now. and he did say itll slap until it warms up.
