Default Rhino Engines

Just got a quote on a LT1 long block from Rhino.
Anyone have experience purchasing these motors for Rhino?
Price is right, I make them verify it's a Corvette 4 bolt main
block with the right castings numbers on the block and heads.
Appricate any Forum member comments before I pull the trigger.

What's the quote and what are the specs? Have you thought about going to a splayed two-bolt?

C4, Corvette 4 bolt main block ?? Maybe a C3 4 bolt block. I dont think any C4s had 4 bolt mains.

C4 corvettes come with 4 bolt mains at lkeast the LT1 motors do for certain, it is one of the things that differ from the rest of the LT1 engines in F and B body cars.

yes, LT1 and LT4 Corvettes are 4 bolt main blocks.
They are quoting $2050 for a LT1 long block wt shipping & $450 core-
but would like to know if anyone has any experience with Rhino Engines?

I've never heard of them, did you find them on-line or are they a local shop to you? If you want a good opinion on the quote though you'll need to get into some specifics, in terms of all the parts used...crank, rods, pistons, heads, valve-train, cam, etc...

EDIT: Just looked them up, so this is a factory-spec replacement? If so that's a good price...sorry I can't help you with experience with them though

Youll be Ok with a 2 bolt main unless youre really trying to build power and twist it high.

1985= standard gen 1 chevy 2 bolt main block
1986= standard gen 1 chevy 2 bolt main block, add 1 piece seal, right hand dipstick
1986 1/2 = same as above, but adds aluminum heads (cast iron clones),
1987 = same as above except adds roller cam, lifters, spider, center bolt covers
1988 = same as above except better alum. head combustion chamber
1989 = 4 bolt block, roller cam, 58 cc D port heads, 1 piece seal, dished pistons, center bolt rocker covers, windage tray
1990-1991 same as 1989
If they claim it is an L98, and it has 4 bolt block, it is the latest version

Been doing more digging: Golen Engines 383 short block for $3000.
I like being able to talk to the guy who is buidling the motor and not
a salesman filling an order. Jasper and Rhino LT1's are probably great
for the money on a daily driver but apparently no one had any actual
real world experience to report. I'm not totally confident I'll get an
actual Corvette 4 bolt block since they both use the same 327 casting
number.

Im wondering if the L98 specs arent wrong Ive never heard of a 4 bolt L98.

Rhino sounds like a basic stock rebuild. Bore hone, generic rings, bearings, etc. Are they using new valvesprings, retainers, things like that?Guess for 2k you cant expect much outside of that. Some rebuilder houses supply new parts such as those, many reuse them .
Hit up Google.com and enter their name, youll find feedback.

I've been told the 90 and 91 L98's have flat top pistons, to get the CR up a notch. Mseven can verify this,
since he has had his 90 engine apart a time or two. Mick, correct me if I am wrong.
BTW, 2 bolt blocks are plenty anyway, unless you are going to spin it
to 7 or 8K. And they are actually better than the 4 bolt blocks if you
have it made into a 4 bolt w/spayed bolts and billet journal caps (from my machinist).

that is correct 90-91 has a flat top w/small valve reliefs. I think either way (4 bolt) is good, but splaying should be stronger.
