Yes , but you will need a tbi intake to fit vortec heads if you retain the 90 TBI fuel system.
it will work I have vortec heads on a 72 400 small block, I had to get the heads reworked for the 400s water ports or steam port and a vortec type style intake will be needed
No way, not even close. Chevy REDESIGNED the engine blocks and the transmissions in late 1999. Nothing will interchange under 1999.
NO it will not. You would need the heads off the vortec engine to make it all work. The 96 that you are talking about should be a VORTEC engine already from the factory. But you may have an early 96 and that is why it is a TBI engine. That was the year they switch to a vortec. 96 TBI no such animal,TBI OBD2 no
The 2000 5.7 Vortec heads are generally similar to the 1999 5.7 Vortec heads, but there may be some differences in casting numbers and minor design features due to manufacturing updates. It's essential to check the specific casting numbers on the heads for compatibility. Additionally, variations in valve sizes and ports can occur between different production years. Always verify the specific application and requirements for your engine build to ensure proper fitment.
Nope, different heads
the 5.7L vortec has about 300hp in a Tahoe/Suburban
NO......
NO. You need a VORTEC engine from the year 1997 to 1999
No it will not. The 1990 engine is all together different and yes it will bolt in But it will not run. You need a VORTEC engine from the year 1996 through 1999.
vortec 454,1996 thru 1999-->>>290HP 410TQ
1999
Should be like any other Chevy small block, 1,8,4,3,6,5,7,2, clockwise that is. The drivers side front plug is #1.
