I'm Awesome
I like 'stock' vehicles, and although I like stock, and prefer to leave this truck as-is (for sentimental reasons), I am also teased with the idea of getting a little more power out of it...
I did some looking around and couldn't exactly find a discussion that covered these questions...
I have contemplated doing a vortec swap which would include a GMPP TBI intake to retain the TBI and everything currently hooked up;
But another though that occurred to me is a 454(tbi) swap;
If I was to do a 454 swap (assuming I use all correct for my trucks model year senders and throttle body) what is different?
(I am aware that stuff like the TBI and injectors are engine specific)
1) Is it unreasonable to assume that a C1500 sport truck and the 454SS used the same engine loom?
2) I would assume that they both used the same ecm - but do they use the same memcal (chip)?
In my mind, those two last questions would be the biggest hurdles if a swap like this was undertaken.
(EG: what would I need to change in addition to the motor that would hook up to, or be a part of the motor?)
I am assuming that the transmission currently in my truck can be bolted behind a 454, and as long as it's period stock (read: underpowered), the transmission should be fine right?
Also, if I found a donor 454 tbi motor, what years use the same injectors/TB ec?
(EG: is a 1995 454 TBI motor the same as a 1990 tbi motor - if not, what changed from year to year)
Hopefully this isn't to big of a query.
