OK, what do you guys think is the easiest way to get 220 flywheel HP out of a normally aspirate L28? There's just a couple problems, I don't want a 3.1 and I want to get atleast 20 mpg.
I think I can get my 83's dry curb weight down to 2700 lbs. So I'm expecting to get 0-60 times in the 6 sec territory. I'd like to hear what you all have to say.

Re: I have a challenge for you engine builders, L2

I'm not an expert, but i listened to enough wise people, to try; get a N42 head of 75-76 280z slap it on the flattop block 79-83 N/A and get carbs, my pref. 70-71 SU's mild cam that should get you around 190HP on wheels
~200Hp flywheel. Stan

Antony,
Are you talking 220 HP gross or net? 220 HP gross is only about a 50 HP increase but 220 HP net is about a 90 HP increase and will take some serious work. 220 HP net works out to about 285 HP gross. You won't get both the HP and your desired fuel economy without fuel injection and an aftermarket programmable ECU - or boosting the engine.
Alamo Autosport in Arlington, TX has a customer that got there by using wrecking yard parts - turbo & intercooler out of a Mitsubishi, 'O' ringed his head, and installed a new timing chain. Cost $2,500, HP = 220 net. MPG = 20 -21 on the highway driving it easy in 5th. You try to stay NA and you'll lose the fuel economy.
