I m going to tell you to rethink your cam choice. Unless you know what your getting into, big cams are not a budget way of going fast, you will need every Max effort part, and a good gear to get it moving. Again if you know what your getting into then by all means go for it, just when ever I see a thread asking about the t Rex or anyother big cam I always say stay away.

He's right, you need the parts to work together.

What other mods have you done? That cam with those heads by themselves wont help unless you have mods to support them

op listen im going to just say your kind of new to ls cars, if your not my bad, but there are so many people that just think the biggest cam will make there car the fastest and make the most hp, that couldnt be more wrong, when i first put in my ms4 cam the car was a dog, i didnt know what i was doing at the time i just got caught up in all the big cam bs.i will tell you if you dont have the mods to run this cam your car will be a dog as well, i will say if you set a big cam up right they can fly, and if your looking for a big cam sound you can get that in a much smaller pro file .if i could do it all over again i wish i would have went smaller, but im getting this car to run to show what this cam can do when it is set up right. the best move you can make is call eps , and get your heads set for a cam they set up for you.

To answer the OP's question, you may need to flycut. You'll need to be ready to measure PTV to be sure. Don't risk damaging your motor and just do it to be sure.

Well it's going too be a stock block street car/drag car not a dd I kinda know what I'm getting into its why I'm asking if i need too bc I know its kinda a hit or miss with this cam some people can get away with out it and some people have too I'm planning on having the heads ported and polished running a 90/92 when I can find one along with some 42 lbs injectors… and yes I'm fairly new too ls1's I've only been around them for a year it's why I ask questions if u don't know something there is always some one that does ya know and I was planning on running a 4 10 till I broke the ring and pinion for the ten thosandth time and up it too a 4 30 gear for when I switch too a 12 bolt or a 9" can't make up my mind on which one I want lol

I agree with Rare96LT1Formula, PTV clearance should be checked with any decent sized camshaft installation. A fraction of your time spent checking could save you alot of money.

408 what does your post have to do with this thread LOL.if its a drag car by all means go for it, if you have a m6 go 9 inch for sure.also I hate to say it but in a drag car and m6 the money your going to put in that ten bolt isn't going to last you long at all.if your an auto you can get away with it for awhile but its a ticking bomb.also a good idea would be katech rod bolts, your going to be spinning it very high.as far as the fast intake I would shoot for the 102, unless you can find one with a decent port job or port it yourself.IMO building a drag car requires a lot of the time at the track. If you listen to everything you hear on the internet you will just waste money.good luck though man,
