educated opinion needed - trick flow 420hp 23 degree kit/bolt on
is this kit worth the money. i plan on buying this kit along with magnaflow CB exhaust, the moroso CAI, and the pacesetter LT headers. would this be a good setup for the money ? around 2600$. what would you reccomend. also, is this kit a bolt on it where everything is included and i would basically just bolt it on. thank you - will

Where are you finding the "kit"? The Trick Flow heads have 62cc combustion chambers. They are intended for blower motors, because the compression ratio is going to drop about a full point compared to the LT1 heads. Out of the box, they flow similar to the stock LT4 heads, and they can be reworked for much greater flow, and to reduce the combustion chamber volume, but that's an additional cost above what you appear to have in mind.

They will work, but the above post clearly stated why they are not a good idea on a stock motor. There are other cheaper options out there and they will yield you better gains for what you plan on doing. For example, you can get your stock heads reworked by this guy for a reasonable price www.eportworks.com

On a stock bottom end they will be lazy from the drop in compression.

Clearly he's not looking in the lt1 section. What he's looking at is a top-end kit for Gen1 350's. The 420hp one is rated on a 383 anyways.
For LT1 top end kits, you'll have to look to someone like AI or eportworks.com. The kit you are looking at will not work.

Those heads can be made to flow in the 330 range so it seems the 420 was on out of the box heads.
If ya had 330 CFM on yours with the right set up ya could put down a LOT more than 360 'cause 330 will make 678FWHP with everything else right.

Consider the ratings you see in catalogs are dyno tuned no accessory flywheel numbers tested in the same configuration I think most will agrtee with me the stock f-body LT1 will put down something over 360 . Keeping that in mind that kit really looks bad even if it did fit

No 420fwhp is easy but 420rwhp with a 350LT1 takes a little more work but easily achieved with the right heads/cam and dynotune. I just put the new Trickflows on my 355" LT1 but they are heavily worked and will have some #'s very soon. Later Clint
