WINDYCITYJOHN400 Posted March 29, 2011 Report Share Posted March 29, 2011 Go to the product reviews section and read the post titled "Trinity Blows" before you buy any dome from Trinity. You'll want to get some from ANYONE else other than them. Quote Link to comment Share on other sites More sharing options...
sheefreak Posted March 29, 2011 Report Share Posted March 29, 2011 If you don't want to scrap the trinity head, you can get blanks from them and send them to a real builder to get cut for you. Quote Link to comment Share on other sites More sharing options...
Burt Reynolds Posted March 29, 2011 Report Share Posted March 29, 2011 (edited) You can get the domes from trinity. The stage 4 head is a great product from a bad company Edited March 29, 2011 by Burt Reynolds Quote Link to comment Share on other sites More sharing options...
americanmusc1e Posted March 29, 2011 Author Report Share Posted March 29, 2011 So I should start saving for a REAL coolhead??? Quote Link to comment Share on other sites More sharing options...
Burt Reynolds Posted March 31, 2011 Report Share Posted March 31, 2011 (edited) I have ran a few trinity stage 4 heads and have had zero problems out of any of them. You can buy domes from trinity racing. I am weary of ordering anything from them,but if all i needed was a set of domes,i wouldnt hesitate. I would never buy another head just to get away from a trinity,they work well. Edited March 31, 2011 by Burt Reynolds Quote Link to comment Share on other sites More sharing options...

I never said the HEAD was bad....only Trinity's Dome designs are an issue. You can buy domes from Trinity....but Why? If you take a couple of simple, basic, engine building measurements and call a site sponser, they can cut a custom dome for your motor to give you the exact compression and squish you need to make max HP with the best reliability you can get. Just picking a CC size doesn't guaranty you won't have issues due to the dome shape. Why get "A DOME" when for about @ $60 bucks more, you could get "THE RIGHT DOME"?

I could actualy add a little to the trinity thread,but nothing thats posted in that threat is going to make the trinity domes run bad. Basicaly what im trying to tell this dude is that the trinity head works fine and i personally wouldnt spend 50 to 60 bucks more just to have a different brand name on the head. If i had to buy a cool head,i would go with noss,if i already had a trinity,i would keep it. Edited April 1, 2011 by Burt Reynolds Quote Link to comment Share on other sites More sharing options...

robert.b.west Posted April 1, 2011 Report Share Posted April 1, 2011 I have also heard trinity domes are bad. The squish angle is wrong or something. Can't remember. I haver heard many complaints about there domes. I personally would not get trinity domes. Quote Link to comment Share on other sites More sharing options...
