Calm down guys.......I was just being funny.

My buddy had a stone stock 454ss in high school and we took it to the track and it ran something like 15.60's or something. I remember laughing my *** off at him cause he told everyone it had to be a 12 second truck. I'll give him a little credit, it felt like it was gonna run a 12 something for about the first 30 feet when it hooked.

At the time I had a 89 Formula 350. Remember the ol'trusty L98 days! Only reason why I bring it up....the 454 truck and the tpi 350 had about the same powerband.....felt like it was gonna go pretty good then the tac would die around 4500 rpm.

I know this place is a sanctuary for die hard ls guys, I just feel obligated to give people **** when one has to replace a rat motor.

...and if you think a fresh 6.0 would feel more snappy than a 454 you're on meth.

...and if you think they "made a lot of those trucks" (referring to the 1990 454ss) you're on a good "houston cocktail" For those that don't know about the Houston Cocktail it is a proper mix of hydrocodone, carisoprodol, alprazolam.

Regarding the drug talk, I have to keep up the persona created by GeorgeC.

They had the "peanut heads" with tiny ports and small valves was the problem. It may have had cubes but was breathing through a straw. '73 & '74 old iron heads #049 & #781 were the ticket for a cheap swap. A set of heads, mild cam and headers and its a beast. Big block torque is awesome!

And the junk TBI setup really is nothing special either..... the 90 models still used the old 4 barrel intake with an adapter plate lol. A 454 can be fun...... but peanut ports, 7.8:1 compression and a cam that is almost just round does nothing for power lol. 10:1, good heads, a decent cam.... hang on!

Yep. I had an 1985 rcsb 1/2 ton in college with a 0.030 over 454 in it. Mild cam and some home ported 781's. I wish I had digital pics of that truck cause it was crazy clean. I burned up a lot of fuel and tires with that thing for sure.

RCSB '73 here with ported 049s, headers and a 750 holley. It was so much fun suprising the little 5.0 mustangs in the mid-late 80s!
