I have searched, but I have not really found the answers I am looking for. This question has been a long time coming. I figure that most people really do not care if they have to buy an aftermarket hood. Me on the other hand, I really enjoy a stock appearance. Stock wheels, stock hood, stock stereo head unit, etc.

I currently have a 1992 Z28 with the 5.0 TPI. If I have read correctly, I will NOT be able to fit a much under the stock hood. I don't want to bring up the build the TPI up debate. I am going to pass on building the TPI up due to the fact that TPI and lopey idle don't mix. I would like a simple in and out swap. A crate motor to be precise.

I am looking to get around 300-400 Horsepower, and I am planning on running the T56. I am not looking for a power adder, rather a fresh engine with a little more power and a nice lopey idle that I dream of

I am thinking a budget 3K-4K would be fair.

Has anyone else gone down this path and found a solution?

 

anything will fit, in my opinion the only clearance issues that arises is when it comes to the intake you choose... that's what will give you clearance issues...

 

I've been building a 412 SBC setup (over the course of years, it feels like).

I've got the block, a smaller dual plane intake, 750 Holley carb and drop base filter and it SEEMS to all fit below the stock hood. I wont know for sure until everything is buttoned up.

The drop base filter is a HUGE must if you even want to get close to fitting.

 

in my opinion the LSX motors are the best fitting/looking swap out there, they totally look factory in there, but I had an old school 355ci in my '91 before the '04 GTO LS1 thats in there now, wich had Edelbrock Performer RPM heads & MPFI(multi port fuel injection) w/ k&n CAI (cold air intake) fit /looked great under the stock hood too!
I still have this fuel inj. system & cold air intake for sale for 1/2 price of new if youre still looking & it comes w/ everything that youll need to upgrade the air/fuel sys. in your fbody, just fyi.
