Thanks for the reply Ken,
This truck belongs to a friend of my son. He is on a low budget so we will probably keep the intgral heead and 2SE as long as there are no cracks in the intake. I took a glance at the emmissions plumbing and it is in bad shape. I'm sure this is his main issue. There is no emmissions testing here; not even a yearly safety inspection.
The cheapest route will probably be to remove the emmissions stuff as it is not working anyway, then put a high quality kit in the carb. I was hoping a 2G would bolt up since this would be a nice performance upgrade and I have had good luck with the 2G on some other cars.
Best regards,
Scott.
