Back in the day, I ran a 1970 LT1 in a Z-28 Camaro... It was a great car and engine. I updated the cam to a Racer Brown STX 21 solid lifter(I believe), and the 350 then made right at 400 horsepower and revved out to 7000. Roller rockers were definitely needed then as the Racer Brown cams increased action, burnt up factory rockers. That cam really brought that engine alive. The factory cam was plain lazy...

[@albertgaspar627]

well, the OEM cam was meant for operating AC and vacuum options and a wide range of driving styles. Mellow in a 350, less so in a 301 with a 780 cfm Holley.

Does the LT4 make much more power than a standard LT1? I know they had a hotter cam and slightly better heads and intake. I had a customer for years that had 2 LT4 Corvettes and I was impressed in the 1990's by them. One was built by Doug Rippie though and was a 383. It was the only C4 Corvette that would keep up with the later C5 and C6 cars!

@@richardholdener1727 well what do you think would make more power? Stock, and modded? My money is on a hemi Stock, and a ls1 when the mods start.

[@andyharman3022]

Yep, I knew the LS1 had it all the way. Only the LS6 is stronger than it for a factory 5.7L SBC.

[@shadowopsairman1583]

For Torque it looks like the L46 and LS1s are the way to go.

[@leematson8484]

Holy crap-where did you find a LT5 not still in a car?!

[@allanb3222]

I'm sure one of his buddies at westech has one!

[@weskirkland5850]

Do a camaro LT1 with aluminum heads N/A with the lt4 hotcam.

[@LaserLuther]

I love all of them.

The most powerful 350ci built is the one you build😉
