My brother has a '87 IROC: He took the 305 to it's limits with a SLP T-ram intake, twisted wedge heads, mid sized cam, SLP headers/cats/catback, speed and marine TB, TCI 3000 stall, 3.42 gears, custom chip, full BMR suspension and a bunch of other stuff that netted him low 14's @ 98-99mph.
Pitiful.
He then dropped in a crate 350 with 10 to 1 compression and got it into the high 12's with those same parts. lol

Now that I think about it, I believe SLP use to sell those seperately. One of the best manifolds for the TPI motors.

There have definitely been 305 builds that moved out well. A guy in our car club in college, years back, built his 305 Firebird and ended up running 13.8 @ 104 with it. Carbed motor, stock bottom end, 5-speed. He could never launch it well on the street, but from a roll he ran door to door with my bolt-on LT1 Trans Am.

I've always had good luck with 305's. Hell I had a stock one with only exhaust that was as fast as this turd I've got now when it was stock. They def are sorry but they're hard to kill!

I love 3rd gens but thirdgen.org is just too comical. The word "MULLET" is censored from the website as if if were profanity ![The Jester](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_jest.gif)
and yes some of those old farts are still modding the TPI and spend $$$$$ to run 12's and not even make 400rwhp

Yeah the T ram is a badass looking manifold but the TPIS miniram and holley stealthram outperform it above 5500rpm. He got the very last one SLP had left when they were selling them, paid like $2,000 for it. The hardest to find part is the eccentric pulley linkage that a auto car requires. He has been offered $3,500+ dollars for that intake by collectors multiple times but refused to sell. Even though he now has a Stealthram intake for it sitting on a shelf.

The boat is a "keeping up with the jones" thing combined with brotherly competition. We have ALWAYS competed to see whose car was faster and who was the better driver.
I got the GTO and he was faster stock, then I modded up and beat him, so he dropped the trick flow heads and got AFR 195's and a bigger cam, so I did a heads/cam and one-upped him again: he was planning a LSx swap until I did the full 402 build and got a nitrous kit. lol so he gave up on the car and got the boat.
A badass 26' Eliminator with a stout big block and more aftermarket mods then you can shake a stick at. Couple thousands watts of stereo with 12 speakers and 3subs build into the plush custom interior plus 78mph on GPS with a jet boat like midrange punch. The mods had to have cost as much as the cost of the boat itself... Seriously. He got a screaming deal on it for $18k and only a few years old... though he had to drive 4 states away to get it out of lake havasu.
!!! Now he is badgering me to buy a offshore boat myself so we can race each other. !!! I can't swim in the deep end of that money pool!!!

My brother has an 87' z28 with a 305. It has intake,full exhaust,a cam,700r4,some sort of heads,and 3.73's and with all that he bet that my bolt-on 98' trans am had no chance. I'll tell you like this my buddies tpi gave me a better run.
