Re: need opinions on Nitrous combo
No problem with 9's. I have had less of a combo go mid 10's on small shots. Those cubes and heads can do 10's on motor and a 200 shot well into the 9's
Is the block already purchased? I would prefer to see billet main caps in the little m with a nitrous combo but depends on the shot size
I wouldnt spray more than 300 without watching the caps for walk. Thats about where my friend seen cap walk on his shp block.
Other than that should make steam. Afr 227-235 would make more power tho. Should have shaft rocker system anyway so the valve spacing in the 227-235 head isnt an issue

Re: need opinions on Nitrous combo
10 pt cage and diaper. no funny car type hoop for cage because I am a big guy and it would be very hard for me to get in or out of the car. I do not have a removable steering wheel and want the car to still have some sort of street drivability. car still has factory carpeting, p/windows, p/locks, p/mirrors. windshield wipers work and so does the horn. the car will be driven on the street for special occasions. Short mileage for certain.
The block will be studded mains and heads.
as for a shaft rocker setup, I will go with a LGM system.

What are you running for seats + restraints?
Sounds like a wicked cool build. I wish I had gone with an SHP block.

Re: need opinions on Nitrous combo
sorry I do not have any pics of the new cage. I like comfort when I drive so I am using a 4th gen seat with inserts in the shoulder/headrest area to make for a clean factory looking installation for the belts. I use gforce belts that are due to be replaced. I have a lot to do on the car to get it ready for the new engine. the suspension has to be dialed in yet. That is where most of the time will be spent. making sure the car goes straight, stops straight, and does not do anything silly like wheel stands. I will not pour the nitrous to it till I am satisfied that the car is good to go using it.

Re: need opinions on Nitrous combo
need to get the car low while still making it hook. 3.42 gear for sure. front suspension limiters with some GOOD front shocks that can be dialed down to be very slow on extension- if you dont have the strange d/a's up front. it will want to wheelie. also, you need an anti rollbar such as the wolfe or something.

Re: need opinions on Nitrous combo
Yes that is a concern, finding a good set of 1 7/8 headers is a challenge. I know Hedman makes some , but I dislike the collector setup on them. I would probably have to have a custom set made. Since there is no room under these cars for a real effective exhaust system that would quiet the car down. I will have to run a small bullet type muffler off the collector.
One of the reasons I went with the 220 heads was for the standard valve train lay out to stay away from a shaft rocker system and to keep from going to a spread port exhaust and trying to find custom headers for that also. The 220 head's exhaust port size would work better with my current headers than the larger ports for the 227 and bigger heads. Some tough decisions were made for this combo. Some I wish I had more info before pulling the trigger on some of the components purchased.
I did discover the LGM shaft system that I will use over at YB. I have been looking for feed back on them and all the responses I received have been positive. Plus the price is $800 vs $1100+ for Jesel or T & D. I made some mistakes on the choice of components, but I do believe that they are small and fixable in due time. I have a pretty solid foundation to start and build on at least. Thanks for the replys guys!

Re: need opinions on Nitrous combo
I ran lgm's in my turbo car. Great bang for buck
Only other thing i can recommend if you plan on hitting it with alot of spray is upgraded heavy duty valves in the heads. Idk what base valves are used in the heads but a heavy nitrous deal has alot more heat and pressure to deal with. Heavy duty/severe duty stainless valves are a good idea for longevity
