need help with high rev

i have a 90 iroc 350 just put the edelbrock high flow intake and high flow runners on. went to start and is rev ing at around 2 grand. check the timing twice, thats good. i think maybe have a vacume leak. any suggestions...

BIG vacuum leak. Track it down and fix it, don't drive it like that you'll do damage.

i had crazy revving that high once...ended up my vaccuum line going to the brake booster got jolted off since I was messing around in the engine bay I knocked it right off since theres no clamp on it...maybe check that. Good luck searching.
