In conclusion, go with a 92-93 LT1. They're MAF-less, but they still have the optispark system (all LT1/4's have optispark). Dont spend 2k on a LT4 top end from summit when you can spend $1500 on a set of ported stock heads and a custom cam, and make twice the power of an LT4 topend.
He can go MAFless on any year of LT1, all he needs is a good tuner. He can also spend the cash for an aftermarket individual coil set-up. There are two types out there, and I know two people over on TWR are running such a set-up on their LT1's.

True, but the Opti really isnt as bad as alot of people make it out to be. ALOT of fast cars are still running the optispark, the only bad thing about it is its location in reference to water damage, its so low in the motor that water can splash up on it if you dont have it sealed well and leak into the cap, causing the contacts to get corroded and take a crap. That and the water pump can leak on it.

As far as being MAFless, if he's got the money to spend on going through all of that, he might as well just man up and go with an LS1 to start out with. I love my LT1, but if I had the chance to have an LS1 instead, I wouldnt hesitate a milisecond.

but what exactly is wrong with a maf? why is everyone suggesting he go maf-less? from the research ive done on the topic, id much rather have a stock MAF setup than a speed density setup. much easier to tune from and always compensating for variables in the weather and tons of other factors.
There are two really good reasons to go MAFless:

1. The engine compartment or design of the intake track will not allow for a MAF to be placed within it.

2. Forced induction or high HP cars do not runs MAF's because of the restriction it causes along with exceeding the MAFs ability to accurately report airflow.

Tuning a MAF set-up is actually more involved than a MAFless. The reason MAFs exist is:

1. They increase fuel efficiency during transient throttle positions.

2. Allow for degradiation of components during the lifetime of the engine

3. Safety of the engine when any of the following takes place, bad fuel, bad injectors, or poor airflow. Really important if you run wet/dry N2O kits.

No doubt, but he should at least aim for a 95 on up which is vented.

As far as being MAFless, if he's got the money to spend on going through all of that, he might as well just man up and go with an LS1 to start out with. I love my LT1, but if I had the chance to have an LS1 instead, I wouldnt hesitate a milisecond.
The tune costs the same no matter what, and it is cheaper parts wise to go MAFless, ask me how I know The LS1 would kill him in both parts and costs.

for what Royalty is planning on using the LT1 for, it definitely seems that he should use a MAF. im not a mind reader but it doesnt sound like he's planning on using a big power blower setup and from his research he has already learned he can use a 93-97 LT1. therefore there is room under the hood for a MAF.

everyone knows MAFs are ridiculously priced from the factory but used ones are everywhere you look these days.

I am looking at the fact that he is going to have a fabricated intake system. The more pieces the more it costs.
