The DSS cnc block is just a bunch of fancy jargon to upsell a bunch of nothingness.
A stock block is a stock block no matter what you install in it.
It's why you will find most guys here don't invest money in fancy parts in one. Instead of an inexpensive bang, you have a really expensive one.
The injectors are probably 42's, not 44's (not sure if 44's even exist).
With just the 347 and no supercharger, the car will need 30's to run right.
The pms shouldn't be necessary with the right meter and injectors. I've seen R block 347's that made nearly 500rwhp at 7500rpm run 10.40's with solid lifters without any tuning, i'm sure the computer can handle whatever cam you are talking about.
Be realistic, are you really willing to put the car back to stock again? People say that all the time, but after swapping a motor once, you may not want to do it twice, people say it all the time, but most just hand the next guy crates of the old parts and that's how the stock stuff gets lost, sold or junked.
You don't need to take a 200rwhp car and turn it into a 550rwhp car to have fun. That's a 350rwhp gain all at once...
Besides, you say you don't have the budget for
suspension, that 500rwhp is going to turn your car into a pretzel.
You need a complete
suspension for that much power, you also need better bigger brakes, which in turn will cost you to go 5 lug (or buy expensive mediocre 4 lug parts) and then you will need new wheels. You will also need a trans for sure too, there is another 4g's...
It's a slippery slope.
My advice if you aren't all in, is just stay off the slope completely, do a nice h/c/I setup, some nice
suspension upgrades and enjoy the car.
Anyone that comes to look at the car one day will know you have taste and sensibility.
