looking into a future 5.3L build.. Hello everyone, im sorry if this is in the wrong section, i tried my best to put it in the right spot
I need some help planning a future project...
I was planning on swapping an LSx into a 2nd gen camaro before i found a good deal on my current car (1970 Duster w/ a 408ci) but that things just too much for a daily driver, mostly because of its gas mileage, id say im getting 8city/15hwy now...
So, my next project is going to be some 2dr 4 seater chevy and put a 5.3L in it with a t56 6spd. The whole goal of this project is to make a good daily driver with some good power. I would like to see about 15-17mpg city and about 25mpg hwy if this is possible with what im thinking...
5.3L short block
heads/cam/intake
twin turbo on lowish boost
Now that you've got an idea of what im thinking of doing here come the questions..
Do you think its possible to achieve the mileage if i keep my foot out of it?
Can i put aftermarket LS1/LS6 heads on it? (im aware of the smaller bore in the 5.3, but will any gen III head work)
Would i need to do anything to the lower end to make 'fair' and reliable power?
Thanks for reading and hopefully giving me some advise, i appreciate it!

After H/C/I, if you looking for a daily driver with "good power" I don't think turbos would be necessary. Unless your goal is to build a turbo engine, the 5.3 is a very reliable engine and with a proper size cam you would probably be around your mpg target.
And btw LS1/6 heads will bolt right up.

If youre thinking about a twin turbo set up, switching the heads will be idea for compression. 5.3s are a much much cheaper version of the ls1. I bought mine with relatively low mileage for $270 after tax. Its the poor mans ls1 lol
