Engine specs
I am looking for specs on the GM 5.3 LS 327/327 High Output 19165628. I'm not sure where to look to get the information that I'm looking for.
On top of that, I had other questions about part interchangability. For instance, would a set of LS1 heads and/or camshaft work on this engine? Could you use a LSX FAST intake?
Lots of questions, not many resources that I could find. Anyone know where I could find some answers?
- Specs for the heads (valve sizes, combustion chamber size, intake runner size, etc)
- Specs for the block (part number, type of crankshaft, type of pistons, deck height, etc)
- General specs (engine dimensions, compression ratio, etc)

5.3L gets over 400 hp
Corvette Fever- Project C4orce- Have you heard?
(Understand that my arguement in favour of the larger
displacement versions is based on value-for-performance
when shopping for used powerplants.)
As the engines evolve year to year, GM applies new model designations.Corvette Fever- Project C4orce- Have you heard?

A fair degree of engineering information about the models is available
from GMMediaOnLine. The link provided is to specs for the 2008 line-up,
but earlier years remain available by clicking Previous Models in the header.
Specs are provided in both MSExcel sheet and MSWord doc layouts
by clicking the desired format (SS or Win) .
Be aware that there are RWD and FWD varients of the 5.3. As well,
there are also Al/Al and Fe/Al block & head combinations. Probably
not relevant if you are shopping the crate version but worth knowing
for those who browse the take-out counter.
I can not help with information about parts interchangeability in this
series. Perhaps LS1.com is the place to go?
Incidently, I am still waiting to hear from someone who has acted on
my thought about packaging a 3.27" stroke in a block with a 4" bore.
I still haven't heard of anyone taking up my suggestion of playing
'mix-'n-match' with bores and strokes. With a 3.27" stroke and a
6.278" rod, interesting things become possible. In a V8 block with
a 4" bore, a 3.27" stroke gives a displacement of 5.4L (329 ci). Such
a combination would produce redlines of the following values
.

- 7,350 RPM (Equivalent to the PS of 4,000 FPM that many tuner
products enable. - 8,500 RPM (Equivalent to the PS of 4,600 FPM that the LS7 has)
